Re: Computer Algebra
Does any one here know much about computer algebra packages?

Re: Computer Algebra
Here are some very good lecture notes

Re: Computer Algebra
I use Pari for most of my mathmatical curiosities. It's not really able to do solving for you, at least not to the extent that Maple of Mathematica, but it's free, and it's really fun to do something like 12345! and get back a huge 4688 digit number.

Re: Computer Algebra
FYI John, don't feel like you're posting into a vacuum, I for one am taking notes. Just not enough time to process what you've put up just yet.

Re: Computer Algebra
I glad to see I am not posting in a vacuum. This discussion isn’t really related to my posts, on orbital mechanics. I just thought I would see who was interested in computer algebra systems here, since I was doing some reading on it recently. It also gives me a place to store some good links for future reference.
However, If someone learns these systems well enough, it could save some work in the derivation of various formulas. It also allows a person to check there work. More relevant to my posts on orbital mechanics is the software package MATLAB. MATLAB is primarily used for numeric computations. However, it does come with a symbolic package that uses the MAPLE kernel. For anyone who can’t afford MATLAB there is a freeware clone called [http://ta.twi.tudelft.nl/nw/users/vuik/ … lones.html]octave. Any code I write for MATLAB I will try to make sure it runs on octave as well.

Re: Computer Algebra
I've got acopy of Matlab R11. I suppose that if someone wanted to use if non-professionally, there's a chance that it might just fall into my CD burner and a copy might fall into an envelope.
Whoops.

Re: Computer Algebra
This must be the program [http://pari.math.u-bordeaux.fr/]PARI you are talking about.
