(symmetric) Sparse - Sparse Multiplication

I found "mkl_csrmultcsr" but as I understand both A and B must include full storage of data (upper + lower diagonal terms) whereas I have A & B and only upper diagonals stored.

Thanks

Bulent,

I do not see the function for such computation. I can create a feature in the internal database, so our engineer team can check it in the future release.

Thanks,

Chao

That would be great if you include it the list of developments.

For a typical finite element application, we usually deal with symmetric matrices which saves us a lot of memory and computation time. In such an application (Eigen sub-space solution), I need to perform matrix multiplication of 2 sym. sparse matrices.

Regards

For this feature request, we have some questions:

"By computing the product of symmetric sparse matrices and getting SYMMETRIC SPARSE result"

In many cases, such a product is non-symmetric, and dense. Does you some mean some specific matrices to be multiplied?

Thanks,

Chao
