The current git has routines for constructing sparse matrices (ie:
gsl_spmatrix_{get,set}) for both triplet and compressed storage formats.
This should make it fairly simple to pass the relevant arrays to other
sparse solver libraries. I've personally interfaced gsl_spmatrix into
the Lis, pastix, and mumps libraries (haven't tried umfpack). All thats
needed is a simple wrapper routine to call the external library with
gsl_spmatrix.
