Sparse Complex Matrix Multiplication

Hello,

Let's say A and B are sparse matrices with complex values, which are stored in sparse handles (CSR format). I want to calculate D = A x conjugate(B), where conjugate is the complex conjugate of matrix B entries. Is there an efficient way to perform this multiplication? Right now, I have to export the sparse handle that contains matrix B to a CSR 3-array format, change the values to complex conjugate, create the handle again, and then perform the multiplication. I really appreciate if you can provide a more efficient solution.

Thank you,

Afshin
