sparse matrix - dense vector multiplication

Hello,

I have to solve a sparse linear equation system, but it would be advantageous to use sparse formats also in the stage of building the coefficient matrix.

Does the CULA Sparse have the following operators?

- Sparse matrix - sparse matrix multiplication
- Sparse matrix - dense vector multiplication

If not, what do you suggest to use instead?

These operations are more in the domain of CUSPARSE, which comes with the CUDA toolkit.
