I think that choice ought to be given to the user, in the usual "sparse=True/False" option. If I'm doing a bunch of linear algebra on small dense matrices, it slows things down to have one sparse matrix in the mix. I think the sparse option ought to default to False (i.e., default to dense) since that seems to be the current convention.
