Sparse Blas Matrix Multiplication

Hi,

I have a problem using MKL Sparse Blas Level 3 routine "mkl_dcoomm" which calculates C=A*B where A is a sparse matrix in coordinate format and B is dense matrix. Clearly C is also a dense matrix. The problem is that I would like to perform C=A*B where B is sparse and A is dense (reverse of former case). Is there any other function for this (I didn't find!) or I should change my expression and use same matrix? My question might be very elementary, so sorry in advance!

Thanks for your help,

D.

We don't have such a function to multiply dense matrix by sparse matrix in MKL.
