Hi,
I am wondering if anyone knows of a good program that will solve
algebraic formulas symbolically. I was using Mathematica under Windows
to do this. I need something to solve the equations for bilinear
transform of filters to the digital domain. I can't (don't) have the
patience to work the algebra out by hand (it is not usually trivial,
with large powers of complicated polynomials).
Definately Maxima is the only way to go. It's the LISP engine that
Maple and Mathematica are based on from MIT back in the day. It was
semi-recently freed and it's really sweet. It'll take some work (you
have to use clisp - the other LISPs are broken, and the GUI is a bit
clunkier than most), but it's quite nice.
