Dense matrix multiply sparse matrix by mkl fortran

[nvh10]

Function mkl_sparse_?_mm can compute C := alpha*op(A)*B + beta*C where A is sparse and B is dense.

I would like to calculate C := alpha*A*op(B) + beta*C where A is dense and B is sparse. Please let me know is there any function like this.

Thank you so much!

Thanks for your help!

I found that for every function, the first matrix is sparse which is different from my goal. I am looking for 

C := A*B + beta*C where A is dense and B is sparse.
