gaussian elimination



Hi!

I can't find a Maxima command to triangularize
a matrix (possibly non-square). 
Does any of you know a command that does that?

On a different topic: a new version (3.0) of my package for
symbolic summation is ready up to some minor interface
changes which still need to be made.
It contains fewer bugs, a better interface,
cleaner code, a numerical test for quickly avoiding 
some cases and the Gosper algorithm for indefinite summation, 
which was missing in version 2.0.
I hope it will be included in the next version(s)
of Maxima.
