Hi,
Ok I see, it is not so important I was just wondering. Presently I only need it for dense matrices, fow now I am just using MatDenseGetArray on both matrices and multiply both arrays pointwise, which is ok I guess. For non-dense matrices it may be more complicated.
Best,
Marius

Marius,
No. You may write one yourself. Let us know what matrix format do you have. We'll make suggestion to you.

Hi,
Is there a componentwise matrix multiplication, similar to VecPointwiseMult ?
Best,
