Computer Algebra Systems
A computer algebra system, or CAS, is a mathematics engine that performs the symbolic computations fundamental to algebra, trigonometry, and calculus. Recent versions of Scientific WorkPlace and Scientific Notebook (after Version 4.1 Build 2347) include the kernel to the computer algebra system MuPAD®. Earlier versions included a Maple 5.1 kernal
With MuPAD, you can evaluate, factor, combine, expand, and simplify terms and expressions that contain integers, fractions, and real and complex numbers, as required in simple arithmetic and algebra. You can also evaluate integrals and derivatives, perform matrix and vector operations, find standard deviations, and perform many other more complex computations involved incalculus, linear algebra, differential equations, and statistics. Additionally, you can create 2D and 3D plots of polynomials, trigonometric functions, and exponentials, and you can create animated 2D and 3D plots and explore them with the MuPAD VCAM window.
Features and Capabilities of MuPAD
MuPAD Version. This version of Scientific WorkPlace and Scientific Notebook includes the MuPAD 3.1 kernel. We have created an interface to the kernel to make MuPAD easy to use with Scientific WorkPlace and Scientific Notebook.In addition, the system accepts input and creates output using natural mathematical notation, the basis for our scientific word processors. Performing computations in Scientific WorkPlace and Scientific Notebook is easy.
Computational Functions. Scientific WorkPlace and Scientific Notebook provide a wide range of the graphic, numeric, and symbolic computational functions available with MuPAD. The programs provide ample functionality for both simple and sophisticated mathematical computations involving calculus, ODE, matrix manipulations, statistics, linear algebra, and 2D and 3D plots. Also, you can access additional functions available to MuPAD—even if they don't appear as items on the Compute menu—with the Define MuPAD Name menu item.
Animated Plots. With MuPAD, you can create a variety of animated plots: animated 2D plots in polar coordinates, animated 2D and 3D plots in rectangular coordinates, animated 2D and 3D implicit plots, and animated 3D tube plots in cylindrical and spherical coordinates and vector fields. You can rotate, move, zoom in and out, and fly through 3D plots.
User-defined Functions. With MuPAD, you can create user-defined functions (.mu files) with an ASCII editor, even if you don't have access to a full MuPAD installation. The files are easy to manipulate and are powerful tools for users interested in programming. Working in a Scientific WorkPlace or Scientific Notebook document, you call the function with the Define MuPAD Name command.
Available Functions. While Scientific WorkPlace and Scientific Notebook provide many functions available withMuPAD, not all capabilities are included. Programming packages, certain plot types and options (especially animated plots), and manipulation of the position of highlights and shadows in 3D plots aren't available. Scientific Notebook doesn't have 3D implicit plotting with either CAS. Additionally, some limitations exist regarding the placement of text on plots and the use of different types of plots on the same graph. Iteration and condition commands (such as if, elif, else, fi, for, while, do, and od) aren't available.
