+Performs internal optimizations for oneapi::mkl::sparse::gemm by analyzing
+the matrix structure.
+
+.. rubric:: Description and Assumptions
+
+The oneapi::mkl::sparse::optimize_gemm routine analyzes matrix structure
+and performs optimizations. Optimized data is then stored in
+the handle.
+
+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
+optimizations for ``sparse::gemm`` routine.  In particular, if the shape
+of the dense matrix right hand side, :math:`B`, is unknown or widely varying in 
+subsequent calls to ``sparse::gemm`` then a user might reasonably
+only wish to perform optimizations for ``:sparse::gemm`` with respect 
+to the sparse matrix structure.  However, if one or more particular shapes of :math:`B` 
+is available, then each :math:`B` shape can be provided as an additional hint 
+along with the sparse matrix pattern in the call to ``sparse::optimize_gemm``.  This 
+second version of the API with :math:`B` shape should be callable one or 
+more times and may allow libraries to provide more targeted performance 
+optimizations.
