Hi all,

Michael Berry has kindly agreed to relicense SVDPACK or SVDPACKC for use in SciPy.

Hmm, I thought that sparse SVD was provided by ARPACK, already included in SciPy, and it was just a matter of writing the wrappers. Is that still the case, or is SVDPACK for some reason a substantially easier route/is SVDPACK better or more featureful? That said: I think you're right about preferring SVDPACKC, Stefan. WIth all of the annoying issues surrounding Fortran compilers and ABIs, it seems to me that the less new Fortran code gets added to SciPy, the better. David
