Hi All,
I am newcomer of Octave. Does anyone know how to run SVD (single value
decomposition) on a very large sparse matrix (48000 by 38000)?
Thanks in advance.
Dq :)
I'm currently writing the code to integrate with ARPACK, and I have most
of the eigs function working, but lack of time is making the progress
slow. SVDS was the next function on my list. So at this point I can
forward my eigs.cc code and you can help out in the writing of svds.cc
or you can wait till I get a bit more time to implement it, which will
certainly be in time for Octave 3.0...
Regards
David
