Hi, I'm doing a large matrix multiplication and it gives me a error message of " Not implemented yet". What's this error about? The possible reasons. Thanks.

This has not been implemented yet, because it is much, much more common to have a sparse coefficient matrix multiplied times a dense vector (or set of vectors in matrix form) than to reverse the order and it would also probably be an internal version of dense * sptodense(sparse), so the decreased memory footprint of the sparse matrix would not be retained anyway.
