Copy protection makes a program more difficult to use and adds to the cost of the software. The intention throughout the development of MathViews has been to make it user friendly and easy to use, and to bring you a quality, supported software package. We feel that copy protection is contrary to these goals. </P> <HR SIZE="4"> <UL> <LI><A HREF="mathv_t.htm#Heading1"> Introduction </A> </LI> <LI><A HREF="mathv_t.htm#Heading2"> What Is MathViews </A> </LI> <LI><A HREF="mathv_t.htm#Heading3"> Matlab Compatibility </A> </LI> <LI><A HREF="mathv_t.htm#Heading4"> System Requirements </A> </LI> <LI><A HREF="mathv_t.htm#Heading5"> What's in this manual </A> </LI> <LI><A HREF="mathv_t.htm#Heading6"> Typefaces used in this manual </A> </LI></UL> <H1><A NAME="Heading1">Introduction</A></H1> <H2><A NAME="Heading2">What Is MathViews</A></H2> <P>MathViews is a powerful, high-level, interactive, SCIENTIFIC COMPUTING ENVIRONMENT. It is designed for engineers and scientists who need a powerful visual computational and analytical tool to assist them in solving their mathematical problems. MathViews provides simple access to some of the most difficult-to-program yet most frequently used algorithms in engineering and scientific computing. Algorithms encompass such topics as linear algebra and Digital Signal Processing (DSP). MathViews also has extensive graphical visualization capabilities. In addition, MathViews is compatible with existing Matlab M-files.</P> <P>MathViews serves as a calculator, analysis tool, modeling tool, graphics package, and applications development system combined into one powerful application. The package provides an extensive set of arithmetic functions customized and optimized for technical users.</P> <P>The most unique and time-saving aspect of MathViews is its ability to process arrays of numbers. It provides a comprehensive set of operators and functions for performing real and complex vector and matrix operations, 1- and 2-dimensional FFT, convolutions and correlation, and data manipulation. MathViews also has complex graphics such as polar, linear, 3-D hidden line, and contour plots.</P> <P>MathViews is a command driven program. This means that each function of the program is initiated by typing a command at the keyboard. MathViews is more than just a simple interpreter. Each command is actually compiled as the command is entered rather than interpreted at run time. This feature allows for instant syntax checking of the input to provide immediate feedback. The incremental compilation enables the final interpretation to occur much faster than with any conventional interpreter, resulting in a much faster program development and execution cycle.</P> <P>Most tasks in MathViews are solved by using built-in functions and commands. MathViews can be easily extended by creating new commands using the MathViews language. Programming under MathViews is extremely easy because of its natural language syntax and versatile subroutine structure. </P> <P>MathViews has powerful debugging tools. You can select and execute a specified section of code. You can also single-step your program and selectively trace into or around any M-file functions called by the program. Breakpoints can be easily set using pop-up menus. The breakpoint window quickly shows you where your breakpoints are set. A separate variables window lets you examine you program data. An animate mode lets you view each line as MathViews steps through your program.</P> <P>MathViews library management feature makes building large projects easy. Simply put all the functions of a specific project into a MathViews module, compile the module, and instantly, all the functions in the module are available for use. By contrast, in Matlab each module can only have one function defined.</P> <P>MathViews also fully supports the Windows Dynamic Data Exchange (DDE) standard for communicating with other Windows applications. MathViews can operate as either a DDE server or client. All of the powerful features of MathViews are now available to your other applications. You could, for example, execute a M-file from an Excel spreadsheet and pass the results back to Excel. MathViews supports DDE cold, warm, and hot links.</P> <P>You can also extend MathViews by writing your own Windows Dynamic Link Library (DLL) modules. DLLs provide a common means of adding custom code to applications under Windows. The MathViews DDE layer and Graphics layer are examples of DLLs which can be added to MathViews. You can develop DLLs in any language, i.e. Pascal, C or C++, which supports Windows DLLs.</P> <P>MathViews was crafted in C++ for easy portability to other computing environments. Accuracy is assured by performing all calculations using double precision numbers. </P> <H2><A NAME="Heading3">MATLAB Compatibility</A></H2> <P>MathViews is compatible with Matlab syntax and will execute Matlab M-files. However MathViews will execute Matlab M-files only when all the interdependent M-files are present. The highest level of compatibility is provided when using M-files which utilize only built-in functions of MathViews or Matlab.</P> <P>The MathViews integrated environment is much more versatile than the simple environment of the DOS version of Matlab. Features of MathViews include:</P> <P> Different windows for editing, text output, graphics output, and interactive input.</P> <P> Cut/Copy/Paste of commands and script files; Copy/Print for plots.</P> <P> Back scrolling of text for examining past results and statements in all MathViews windows.</P> <P> MathPad utility for editing multiple M-files under Windows.</P> <P> Building and compiling of MathViews libraries. Multiple M-files can be combined into a single module and compiled into a MathViews library. The library can be brought into MathViews with a single command.</P> <P> Precompilation of M-files and libraries.</P> <P> Execution of a selected section of consecutive statements in an M-file.</P> <P> A mechanism for stepping through M-file statements or selected number of statements.</P> <P> Separate debugging windows for examining breakpoints, viewing variables, and showing the call stack.</P> <P> AutoAssign for automatic variable updates; for example, y := abs(x), when x is changed, y is automatically updated.</P> <P> C syntax for simple/compound assignment(+=,*=,...); postfix operators(++,--).</P> <P> Multiple graphics windows, with quick zoom utility.</P> <P> Subplot utility supports up to up to 81 subplots, in a 9x9 pattern.</P> <P> Easily extensible through Windows Dynamic Link Library (DLL) interface.</P> <P> Fully supports Windows Dynamic Data Exchange (DDE) for interfacing to other Windows applications. </P> <H2><A NAME="Heading4">System Requirements</A></H2> <P>MathViews is designed to operate under the Windows 3.1, Windows 95 or Windows NT environments.</P> <P>Minimum system:</P> <P>PC 486 and up (Math Coprocessor is required - MathViews will not run on 486SX)</P> <P>Windows 3.1, Windows 95 or Windows NT</P> <P>Microsoft compatible mouse</P> <P>20 MB hard drive minimum</P> <P>2 MB of RAM</P> <P>VGA display or higher resolution monitors</P> <P></P> <H2><A NAME="Heading5">What's in this manual</A></H2> <P>This manual explains how to use the features of MathViews to quickly solve complex analytical problems.
