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.

Google .. gauss-jordan eliminations ..

Linear Algebra Class Library ( pre alpha ! )

.. and may be 'ixlib'
