I have fairly extensive sparse functions for octave, they interface
to the SuperLU tools. They perform slightly faster than MATLAB
in some tests and a little slower in others.

My last "release" is at:

http://www.octave.org/mailing-lists/octave-sources/2000/70

I'm working on putting it at octave.sourceforge.net as well.
(I have no personal web space)

I'm slowly working on adding the missing functionality, and
could use help.
