One sophisticated new feature is the new Rsolve function, for solving difference equations (also called recurrence equations). Since serious Mathematica work may eventually be presented to an audience, there is now a special authoring palette for slide shows. There are now tools for comparing different Mathematica notebooks - useful for keeping track of evolving notebook versions. Another basic feature is the add-on package StatisticsPlot, which adds a lot of useful textbook statistical plots.Īlso in this category are Mathematica 5’s improved authoring tools. This is significant because Mathematica may be the world’s most powerful environment for image analysis. One basic feature is support for new graphics file types: SVG (Scalable Vector Graphics, a science and engineering standard), PNG (Portable Network Graphics, a Web standard), and DICOM (Digital Imaging and Communications in Medicine, for MRIs and other diagnostic images).

Mathematica 5 adds a good assortment of visible features, too - some basic and some sophisticated. Although Mathematica 5 performs complex functions automatically, advanced users can override most of its automatic decisions. In the case of differential equations solved with NDSolve, you can choose the solving algorithm yourself and see intermediate results. You don’t usually see any of this - but you will see most numeric calculations running 5 to 500 times faster than in version 4.2. To solve nontrivial numeric problems (ordinary differential equations are a prime example), Mathematica recasts the problem in symbolic terms for the best match to available algorithms, picks numerical precision conditions, and monitors progress, switching methods if necessary for faster results. Much of the numeric speed increase is due to version 5’s algorithm-selection code.

Not any more: with version 5, a few lines of Mathematica code replace pages of C. There used to be a class of problems with which you could work fastest by programming directly in C and using an optimized numerical algorithm library. Always the state of the art in symbolic math, the kernel has been retooled with numerical methods and solvers that compete with the best practices in special-purpose math packages. Text and commands cannot be mixed.Now, 15 years later, you can state your problem as an equation or as a set of equations and conditions, and Mathematica generally takes over at that point and delivers an answer without your programming help. It is essential that there is no text in input cells. To change the style of a cell: click the cell bracket this highlights the bracket then choose style from the menu item Format -> Style Then click and a cell insertion bar will appear. Make sure that the pointer becomes a horizontal I-beam. To add a new cell place the pointer in the notebook window below the last cell. Notice that the thin blue brackets of the input and output cells have differently designed tops. The result will appear in an output cell. This tells Mathematica to process your input. After writing 2+2, hold down the Shift key and press Enter (this is abbreviated as Shift+Enter). Start writing something simple, 2+2 for example. As you start writing in a blank notebook Mathematica forms a cell a thin blue frame will appear on the right of the notebook window. When Mathematica starts up, it gives you a blank Mathematica file. Start -> Programs -> Math Applications -> Mathematica 5.2 You will find Mathematica as follows (this sequence might differ on different campus computers) You need to find a campus computer with Mathematica installed on it (for example BH 209, BH 215). Only minor changes might be necessary for the commands below to work in Mathematica 8. This is the current version of this powerful computer algebra system. This is an old, but still powerful, version of this software.

Which is available on most campus computers.
