1.2. Introduction to Mathcad

In this section, looking ahead a little, we will show how to quickly start working with Mathcad, learn how to enter mathematical expressions and get the first results of calculations.

Rice. 1.1. Mathcad 11 window with a new document

After Mathcad 11 is installed on the computer and launched, the main application window appears, shown in Fig. 1.1. It has the same structure as most Windows applications. From top to bottom there is the window title, menu bar, toolbars (standard and formatting) and a worksheet or worksheet. new document is created automatically when you start Mathcad. At the very bottom of the window is the status bar. Keeping in mind the similarity of the Mathcad editor to ordinary text editors, you will intuitively understand the purpose of most of the buttons on the toolbars.

In addition to the controls found in a typical text editor, Mathcad is equipped with additional tools for entering and editing mathematical symbols, one of which is the Math toolbar (Fig. 1.1). Using this, as well as a number of auxiliary dial panels, it is convenient to enter equations.

To perform simple calculations using formulas, do the following:

determine the place in the document where the expression should appear by clicking the mouse at the corresponding point in the document;
enter the left side of the expression;
enter an equal sign<=>.

Let's leave for now the conversation about more reliable ways to enter mathematical symbols and give an example of the simplest calculations. To calculate the sine of a number, just enter an expression like sin(1/4)= from the keyboard. After you press the equal sign key, the result appears on the right side of the expression, as if by magic (Listing 1.1).

Listing 1.1.Calculation of a simple expression

In a similar way, you can carry out more complex and cumbersome calculations, while using the entire arsenal of special functions that are built into Mathcad. It is easiest to enter their names from the keyboard, as in the example with calculating the sine, but to avoid possible errors in writing them, it is better to choose a different path. To introduce a built-in function into an expression:

Determine where in the expression you want to insert the function.
Click the button labeled f(x) on the standard toolbar (the cursor points to it in Fig. 1.2).
In the Function Category list of the Insert Function dialog box that appears, select the category to which the function belongs—in this case, the Trigonometric category.
From the Function Name list, select the name of the built-in function as it appears in Mathcad (sin). If you have difficulty choosing, follow the hint that appears when you select a function in the lower text field of the Insert Function dialog box.
Click OK - the function will appear in the document.
Fill in the missing arguments of the entered function (in our case it is 1/4).

The result will be the introduction of the expression from Listing 1.1, to obtain the value of which all that remains is to enter the equal sign.

Most of the numerical methods programmed in Mathcad are implemented as built-in functions. Scroll through the lists in the Insert Function dialog box at your leisure to get an idea of the special functions and numerical methods you can use in your calculations.

Of course, not every character can be entered from the keyboard. For example, it is not obvious how to insert an integral or differentiation sign into a document. For this purpose, Mathcad has special toolbars, very similar to formula tools. Microsoft editor Word. As noted earlier, one of them - the Math toolbar - is shown in Fig. 1.1. It contains tools for inserting mathematical objects (operators, graphs, program elements, etc.) into documents. This panel is shown in larger view in Fig. 1.3 already against the background of the document being edited.

The panel contains nine buttons, pressing each of which leads, in turn, to the appearance of another toolbar on the screen. These nine additional panels allow you to insert a variety of objects into Mathcad documents. In Fig. 1.3, as you can easily see, on the Math panel, when pressed, there are the first two buttons from the top left (the mouse pointer is located above the left one). Therefore, there are two more panels on the screen - Calculator and Graph. It's easy to guess what objects are inserted when you click the buttons on these panels.

Rice. 1.2. Inserting an Inline Function

More details about the purpose of these and other toolbars are described below (see section 1.3).

For example, you can enter the expression from Listing 1.1 solely using the Calculator panel. To do this, you must first press the sin button (the very first one from the top). The result of this action is shown in Fig. 1.3 (expression in box). Now all that remains is to type the expression 1/4 inside the brackets (in the placeholder indicated by the black rectangle). To do this, press buttons 1, - and 4 in sequence on the Calculator panel and then, on it, the button - to get the answer (of course, the same as in the previous line of the document).

As you can see, you can insert mathematical symbols into documents in different ways, as in many other Windows applications. Depending on experience with Mathcad and computer habits, the user can choose any of them.

Rice. 1.3. Using the Math Toolbar

If you are just starting to master the Mathcad editor, I strongly recommend that you enter formulas wherever possible using the toolbars and the described procedure for inserting functions using the Insert Function dialog. This will avoid many possible mistakes.

The described steps demonstrate the use of Mathcad as a regular calculator with an expanded set of functions. For a mathematician, it is of interest, at a minimum, to be able to define variables and operations with user functions. There is nothing simpler - in Mathcad these actions, like most others, are implemented according to the principle “as is customary in mathematics, so is entered.” Therefore, we will give relevant examples (Listings 1.2 and 1.3), without wasting time on comments (if you have problems understanding the listings, please refer to the relevant sections of this chapter for clarification). Notice only the assignment operator that is used to set the values of the variables in the first line of Listing 1.2. It, like all other characters, can be entered using the Calculator panel. An assignment is denoted by the symbol ":=" to emphasize its difference from an evaluation operation.

Listing 1.2. Using Variables in Calculations

Listing 1.3. Defining the user function and calculating its value at point x=1

The last listing defines the function f(x). Its graph is shown in Fig. 1.4. To build it, click on the Graph panel button with the right type graphic (the mouse pointer is hovering over it in the figure) and in the graphic template that appears, determine the values that will be plotted along the axes. In our case, we needed to enter x in the placeholder near the x-axis and f (x) - near the Y-axis.

Rice. 1.4. Graphing a function (Listing 1.3)

Compare the contents of Listing 1.3 and Fig. 1 4. This style of presentation will be maintained throughout the book. Listings are snippets of document workspaces that run without any additional code (unless specifically noted). You can enter the contents of any listing into a new (blank) document and it will work exactly the same as in the workbook. To avoid cluttering the listings, the graphs are shown in separate figures. Unlike Fig. 1.4, in the following figures the listing code is not duplicated, and if there is a link to the listing in the caption, this means that this graph can be inserted into the document after the mentioned listing.

One of the most impressive features of Mathcad is symbolic calculations, which allow you to solve many problems analytically. In fact, according to the author, Mathcad “knows” mathematics, according to at least, at the level of a good scientist. Skillful use of the intelligence of the Mathcad symbolic processor will save you from a huge number of routine calculations, for example, integrals and derivatives (Listing 1.4). Pay attention to the traditional form of writing expressions, the only peculiarity is the need to use the symbolic calculation symbol -> instead of the equal sign. By the way, it can be entered in the Mathcad editor from any of the Evaluation or Symbolic panels, and the integration and differentiation symbols can be entered from the Calculus panel.

Listing 1.4. Symbolic calculations

In this section, only a small part of the computing capabilities of the Mathcad system was considered. However, the few examples given here give a good idea of its purpose. It is even possible that by prematurely talking about the simplicity with which mathematical calculations can be carried out, the author lost some of the most impatient readers who had already moved on to solving their problems. I would like to advise them to use the second and third parts of the book as a reference, and for the best presentation of the results, use the fourth part. Below, in this and subsequent chapters of this part, the basics of Mathcad are covered in more detail.

This chapter describes valid Mathcad variable and function names, predefined variable likes, and number representations.
Mathcad operates with complex numbers just as easily as with real numbers. Mathcad variables can take complex values, and most built-in functions are defined for complex arguments. This chapter describes the use of complex numbers in Mathcad.

This chapter describes arrays in Mathcad. While regular variables (scalars) store a single value, arrays store many values. As is usually customary in linear algebra, arrays that have only one column will often be called vectors, all others - matrices. A discrete argument is a variable that takes on a number of values each time it is used. Discrete arguments greatly enhance Mathcad's capabilities by allowing you to perform multiple calculations or loops with repeated calculations.

This chapter describes discrete arguments and shows how to use them to perform iterative calculations, display tables of numbers, and make it easier to enter many numeric values into a table.

Mathcad uses regular operators like + and /, as well as operators specific to matrices, such as transpose and determinant operators, and special operators such as integrals and derivatives.

This chapter contains a list of Mathcad operators and describes how to enter and use special operators.

This chapter lists and describes many of Mathcad's built-in functions. Mathcad statistical functions are described in the Chapter “Statistical Functions”. The functions used to work with vectors and matrices are described in the Chapter “Vectors and Matrices”. This chapter provides a list and description of the built-in functions of the Mathcad package. These functions perform a wide range of computational tasks, including statistical analysis, interpolation, and regression analysis. Mathcad PLUS allows you to write programs. A program in Mathcad is an expression, in turn, consisting of other expressions. Mathcad programs contain constructs that are in many ways similar to programming constructs in programming languages: conditional transfers of control, looping statements, variable scope, the use of subroutines and recursion.

Writing programs in Mathcad allows you to solve problems that are impossible or very difficult to solve in any other way.

This chapter describes how to solve equations and systems of equations using Mathcad. You can solve both one equation with one unknown and systems of equations with several unknowns. The maximum number of equations and unknowns in the system is fifty. This chapter describes how to solve real-valued ordinary differential equations (ODEs) and partial differential equations using Mathcad. Mathcad contains a wide range of functions for solving differential equations. Some of these functions use specific properties of a particular differential equation to provide sufficient speed and accuracy in finding a solution. Others are useful when you need not only to obtain a solution to a differential equation, but also to plot a graph of the desired solution. This chapter describes symbolic transformations in Mathcad. Mathcad reads and writes data files - ASCII files containing numeric data. By reading data files, you can take data from various sources and analyze it in Mathcad. By writing data files, you can export Mathcad results to word processors, spreadsheets, and other application programs.

Mathcad includes two sets of functions for reading and writing data. READ, WRITE And APPEND read or write one numeric value at a time. READPRN, WRITEPRN And APPENDPRN read the entire matrix from a file with rows and columns of data or write a matrix from Mathcad as such a file.

Mathcad graphs are both versatile and easy to use. To create a graph, click where you want to insert the graph, select Cartesian graph from the menu Graphic arts and fill in the empty fields. You can format the graphs in every possible way, changing the appearance of the axes and the outline of the curves and using different labels. In some cases, when constructing graphs, it is more convenient to use polar rather than Cartesian coordinates. Mathcad allows you to build polar plots. Mathcad working documents can include 2D and 3D graphics along with them. Unlike 2D plots, which use discrete arguments and functions, 3D plots require a matrix of values. This chapter shows how a matrix can be represented as a surface in three-dimensional space.

This chapter covers creating, using, and formatting surfaces in 3D space. Subsequent chapters describe how to work with other types of charts.

The graphs described in this chapter allow you to display level lines. These are lines along which the magnitude of a function defined on a plane of two variables remains constant. In Mathcad, you can create a level line map in the same way as a surface plot: by defining a function as a matrix of its values, in which each row and column corresponds to specific argument values. This chapter describes how a matrix can be represented as a map of level lines. 3D histograms provide additional data visualization capabilities. With their help, a matrix of numbers can be represented as a set of columns of different heights. You can show the bars either where they are in the matrix, or by placing one on top of the other, or by placing them along one line. When using other types of 3D graphs, it is necessary to form a matrix in which the rows and columns correspond to the values x And y, and the value of the matrix element determines the coordinate z. When constructing a scatter plot, you can directly determine the coordinates x, y And z any collection of points. Therefore, this type of graph is useful for drawing parametric curves or for observing collections (clusters) of data in three-dimensional space. This chapter shows how three vectors can be used to create a scatter plot. This chapter describes how to create a two-dimensional vector field by representing two-dimensional vectors as complex numbers. (jamesr) Jul 25, 2008 7:01 AM

Hello,
I have a question pertaining to a process that our stress engineers are currently using. After completing a mathcad worksheet, they print to Adobe PDF printer which then pops up the Save PDF dialog box (I can"t find a way to automate this part). They name and save the PDF file. Once created, Acrobat standard opens and they select file save as .PNG. Multiple .png files are created based upon the number of pages in the pdf file that were created. After this is completed the entire set of .png files are inserted into a word document. Inserting the set of .png files are laborous because with their current process, they have to insert the .png files into the word doc one at a time.

If they have multiple .mcd files to convert and place within the word doc, you can imagine how long this entire process takes. I have been tasked with developing a new process.

I envision creating a tool that can select multiple mathcad files and then batching them through this process (MathCAD -> PDF -> PNG -> word) . I am asking for suggestions on how to best accomplish this. Basically, the reason PDF is in the loop is that it formats the .MCD file to their standards. Any other approach with Mathcad produces erratic behavior. The final output must be in a word doc, due to large company policy.

So far, I haven't found any concrete examples of how to accomplish this.

Thanks All,
James

Re: Mathcad ->PDF->PNG->WordDoc
Patrick Leckey Jul 25, 2008 7:13 AM (in response to (jamesr))
Automating MathCAD to print to PDF would be dependent upon MathCAD and its automation abilities. Acrobat can"t force an external application to print something to PDF.
You could certainly automate Acrobat to output a PDF to PNG.
Again, Acrobat cannot convert a PNG to a Word doc, so that part of the automation process would fall out of the scope of Acrobat automation. You"d want to look into VBA for Word to automate that portion.
Re: Mathcad ->PDF->PNG->WordDoc
(jamesr) Jul 25, 2008 7:30 AM (in response to (jamesr))
Malkyt,
There is no option in MathCAD File->SaveAs->WordDoc
You can save as .rtf, .html, or a different version of mathCAD.
MathCAD "s automation gave me a .printall() method. PrintAll prints to windows default printer. I can programmatically change my default printer, however, the hitch is when Adobe PDF is the default printer, the save as PDF print dialogue pops up and requires user intervention. Is there a way to automate this? I saw a silent print method in the acrobat libraries after browsing through the object browser in VS 2003.
Basically, mathcad looks somewhat limited...It looks like I have to print to adobe PDF to format the data...not sure how this process works behind the scenes though. At what point does Adobe take over from mathcad?
Thanks again for pointing me in the right direction
James
Thanks,
James

PREFACE

Effective work of an engineer is currently unthinkable without personal computers(PC) and developed telecommunications facilities. The operation of the PC itself is ensured operating system(for example, MS-DOS, OS/2, Be OS, Linux, Windows, etc.), and to solve applied problems they use special application software packages.

Naturally, a qualified user who has sufficient knowledge of one of the programming languages (for example, C, Pascal, Fortran, Lisp, Prolog, etc.) can independently develop and debug a separate program or a set of programs that allows him to implement the algorithm of his task on a PC. Moreover, in some cases, a highly specialized program developed by the user can work significantly faster than a program from a software package. However, this approach usually requires large labor costs for programming, debugging and testing of each program, significantly reducing the share of creative work to solve a specific technical problem.

To reduce programming time, a large number of application packages have been created, the areas of use of which largely overlap. For the most effective use computer technology it is necessary to correctly select the best software package at the earliest stage of solving an application problem.

The most well-known application software packages currently used in engineering calculations are Mathcad, Matlab, Derive, Maple V, Mathematica, VisSim from well-known foreign companies and packages from Russian manufacturers Open Source Software Dynamics and CLASSIC (developed by SPGETU).

When studying automatic control systems and computational mathematical problems, it is most effective to use software system Matlab with extensive domain-specific

digital libraries (toolbox) and the visual modeling tool Simulink. For visual modeling and simulation in conjunction with real equipment, VisSim is most convenient, a free academic version of which is available at the university. For the analysis and synthesis of linear control systems, CLASSIC is most convenient.

Analytical transformations can be performed by many software packages, for example Mathcad, Matlab, Mathematica, but the Maple V package is considered the most powerful tool for automating analytical calculations. A simpler specialized package for analytical transformations is Derive.

All the above packages are supported and developed by large companies. There are a sufficient number of pages on the Internet where, by the name of the package, you can find libraries of freely distributed programs, tutorials, additions and corrections to new versions of programs (patch), and links to newsgroups.

This tutorial introduces the popular Mathcad software package and contains a large number of examples. When studying the manual, it is recommended to do all the examples on a PC.

1. INTRODUCTION TO MATHCAD

Mathcad is extremely easy to use and easy to learn. Most of the actions required to manage the program are intuitive, and it would take a person who has previously worked in the software to master its basic capabilities. Windows environment, it takes two to three hours.

The Mathcad system has the following features:

The usual method of mathematical notation is used everywhere. If there is a generally accepted way to represent an equation, mathematical operation, or graph, then Mathcad uses it;

The principle “What you see is what you get” (WYSIWYG) is used. There is no hidden information, everything is shown on the screen. The printed result looks exactly the same as on the display screen;

simple expressions are typed on the keyboard using standard keys. For special operators(signs of sums, integrals, matrices, etc.) special palettes are provided;

a large number of well-tested numerical algorithms greatly facilitate the solution of applied problems;

in addition to numerical calculations, symbolic transformations are possible,

has wide graphic capabilities to analyze calculation results, allows you to create animations;

fully supports OLE and DDE technologies, allowing connections with other Windows applications;

convenient help system. By highlighting a statement, function, or error message and pressing , you can display explanatory help information on the screen. Help contains step-by-step explanations on a specific topic and illustrative examples;

in the window, you can use scroll bars, as in any Windows program. Like other Windows programs, Mathcad contains a menu bar. To call up a menu, just click on it with the mouse or press a key along with the underlined character.

To use the symbol palette buttons, place the cursor at the selected location in the working document and click the left mouse button. A small cross will appear in the working document. Then place the cursor on the desired symbol palette button and press again left button mouse and select the desired element (equal signs, relations, two or 3D graph, integral, program structure, etc.). The selected element will appear in place of the cross in the working document.

Below the strip of symbol palette buttons are toolbar buttons that duplicate the main menu commands. When you place the pointer over a button, text appears that describes what the button does. Directly below the toolbar is the font panel, which allows you to change the size and other characteristics of fonts in formulas and text. To save screen space, each of these components can be displayed or hidden using the corresponding command from the Window menu. All pictures in this tutorial show the working document only.

1.2. Examples of simple actions

Click anywhere on the screen with the left mouse button and enter the line using the keyboard

After typing the equal sign, Mathcad evaluates the expression and displays the result

15 − 8 = 14.923

This example demonstrates the features of Mathcad.

Mathcad displays formulas exactly as they are printed in books or written on the board - across the entire screen area. Mathcad sizes fractions, parentheses, and other mathematical symbols so that they appear on the screen as they would normally appear on paper.

Mathcad understands which operation to perform first. In the example above, Mathcad "knew" that the division needed to be done before the calculation and displayed the expression accordingly.

The expression on the screen can be edited by placing the pointer in the desired place and replacing old characters with new ones. After setting the pointer to a free field or other expression, the new result will be calculated automatically.

Let's type the following lines on the keyboard:

b:0.1 x(t):exp(–b t) sin(t) x(t)=

After clicking outside the equality for x(t), the working document will look like this:

t:= 0.5,0.6..20 b:= 0.1

x(t):= exp(–b t) sin(t) x(t)=

The first line provides sequential assignment of the numbers 0.5 to the argument t; 0.6; 0.7, etc. up to 20. It should be noted that the colon [:] on the screen is automatically replaced by the assignment sign [:=], and the period with

comma [;] – sign [..]. The third line introduces the function definition. The fourth line displays the function value for the given argument values in table form. The default screen displays the first 16 rows of the table. To view subsequent elements, you can click anywhere in the table with the mouse and use the scroll bar that appears or “stretch” the table.

Mathcad can set the format for displaying numbers, i.e., change the number of decimal places displayed, change the exponential representation of numbers to a regular notation with a decimal point, and so on. This is done as follows:

Left-click on the table to highlight it with a solid contour line;

select Result from the Format menu; In the dialog box that appears, set the necessary parameters.

For example, the default "Threshold" is 3. This means that numbers greater than 103 and less than 10–3 are displayed in scientific notation. To replace 3 with 6, you need to click to the right of 3, press the key and type 6, or use the incrementing buttons.

1.3. Charts

Mathcad can build two-dimensional graphs in Cartesian and polar coordinates, pictures of level lines, depict surfaces and display a number of other three-dimensional graphs.

Let's consider creating a simple two-dimensional plot that displays the function introduced in the previous section. To create a graph in Mathcad, you need to click on the free space, where you want to place it, and select the Graph item - X-Y Dependency from the Insert menu. An empty graph will appear with input fields for data. In the field under the middle of the x-axis you need to enter the name of the variable t. Now you need to click in the field opposite the middle of the y-axis and enter x(t) here. The remaining fields are intended for entering boundaries on the axes - the maximum and minimum values plotted on the axes. If you leave them empty, Mathcad will automatically fill them in when creating the graph. After clicking outside the graph, Mathcad calculates and plots the points on the graph, as shown in Fig. 2.
