Is there a routine in MKL which computes the multiplication of a diagonal matrix (where only diagonal elements are stored) with a general matrix?

Hi
Which format you store the diagonal matrix? If take the diagonal matrix as sparse matrix.
'
Then you may do searchfrom mkl user manual,

There are some routines to support sparsematrix* dense matrix

like
mkl_?csrmm
Computes matrix - matrix product of a sparse matrix stored in the CSR format.
mkl_?diamm
Computes matrix-matrix product of a sparse matrix stored in the diagonal formatwith one-based indexing.
You maysee if theyare ok.
