Hi Diego
Octave forge currently has sparse matrix functions, based on SuperLU.
This functionality is unfortunately not yet integrated into Octave --
if I recall correctly there there is some discussion as to which
underlying fortran library to use.
If you are interested in the implementation details, look at
http://www.octave.org/octave-lists/archive/octave-maintainers.2004/msg00409.html
where John Eaton expressed his concern over the usage of malloc and
free (instead of new and delete) in the octave forge implementation.
In
http://www.octave.org/octave-lists/archive/octave-maintainers.2004/msg00414.html
Paul Kienzle considered the different fortran libraries available,
indicating that UMFPACK might be a good contender (it is also used by
the leading brand).
Regards
Stefan
