Have you tried using uBLAS lu_factorize and lu_substitute, defined in lu.h ?
Do you know how it compares to SuperLU ? Has anyone made this comparison ?
Also, how large are your sparse matrices?
GluCat ( http://glucat.sf.net ) uses lu_factorize and lu_substitute to
implement division of multivectors. It works well AFAIK, but I have not
compared it to SuperLU.
