Dense matrix multiply tansposed Sparse Matrix?

Hi,

I want to use MKL Sparse to compute a dense matrix multiply transposed sparse matrix. Particularly, if I have input A(dense, m-by-k), B(sparse, n-by-k), I want to compute:

C = A * B'

where C is a m-by-n dense matrix. Notice that the position of matrix is different from what mkl_?csrmm(https://software.intel.com/zh-cn/node/520832) defines. I am thinking about transpose the A and C and transpose them back after computation. But there is too much memory consumption when A and C are both big. Any thoughts on that?

Thanks!
