Actually, it is not exactly a package request.
I just had a look to the list of the available packages and I saw both SuiteSparse and UMFPack. There are few inconsistencies in the presentation (or the choice) of these two packages! And also some minor errors!
First, UMFPack is usually included in SuiteSparse, among others things (CHOLMOD, SPQR, ...), so it may confuse the reader who examine the package list.
Second, the SuiteSparse package is proposed, but it doesn't contain important soft as CHOLMOD and SPQR.
Third, SuiteSparse is presented as using Blas and Lapack ... yes and no. If I'm not wrong, in the whole SuiteSparse package, only CHOLMOD depends on Blas; besides Lapack is not required for any soft inside SuiteSparse!
