Advice to math users - Develope a hand calculated test case to check the accuracy of the SW. This should be something like what you want to calculate. A few years ago a SW company tried to sell the Engineers at GE Engine Control Systems a do it all package. In front of the audience and Developers I put up a test case with a trivial answer that was known as a truth. It failed miserably due to errors in the input translation from the GUI to the real calculations. So before you use a Math Package build a test case - all you need is bad answers to waste time, money or destroy machinery.
Sign on my wall - "To error is human it takes a computer to really foul things up". ! I'm not being picky but just be careful in applying it. Try "R" for fun and games. How about a fast Fourier transform to convert time domain stuff to frequency domain. Helps exercise the neurons.
