Good program for gauss-jordan eliminations?


Hi. You math/Linux nerds out there... What program would you use to do gauss-jordan eliminations for you? I wanted to be able to check the answers on some of my precalc homework. Found a few C functions on the web, but I wasn't sure how well tested these were. I heard there were graphical calculators that do this but I didn't want to spend the money on one yet.

Here's an online one that I use. All its answers have been right for me, and it shows the steps to get there which is helpful as well. I'm not sure about programs for GJ elimination though.

I have a Web app that does this: PolySolve

The source code: PolySolve.tar.bz2 (14 KB)

All released under the GPL (you need to know the rules for GPL).
