 In contrast to other optimization routines in Sparse BLAS domain
 which are done solely based on the sparse matrix pattern, 
 two versions of the ``sparse::optimize_gemm`` routine are provided for preparing different

 only wish to perform optimizations for ``:sparse::gemm`` with respect

 is available, then each :math:`B` shape can be provided as an additional hint
