Description Gael Guennebaud 2012-03-29 11:35:18 UTC
We only have a not very good implementation for a column major sparse matrix. We need a proper one based on the construction of the elimination tree and we need to suport both column and row major matrices. Very useful for true sparse direct solving with a sparse rhs (for instance to compute the Schur complement). Currently the rhs is treated by converting the sparse columns of the rhs to dense ones.
