Mathematica has a Student edition, as well.

Sage is free. -- Gene

Keith F. Lynch: "I've heard good things about Mathematica. Too bad it's so expensive. I've been doing everything in C. I'm curious whether Mathematica is reasonably fast."
HansH>I think Mathematica is a wonderful toy for the recreationalist (especially, with ready-made "black box" procedures for all manner of mathematical situations. For example, if I wanted to duplicate Bill Gosper's "representions of 31415 as sums of four squares" I'd use something like PowersRepresentations[31415,4,2]] and it might even be somewhat faster than his from-scratch procedure but, in general, I'll guess (based on C programmers trouncing my Mathematica-produced output in the past) that you can do things faster in C. ------- Yow! In[36]:= tim[Length[PowersRepresentations[31415, 4, 2]]]
During evaluation of In[36]:= 1.875057
Out[36]= 829
Anybody feel like speedbumming this in C? --rwg _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
