SparseMatrixMatMul

Matrix-multiplies a sparse matrix with a dense matrix.

Returns a dense matrix. For inputs A and B, where A is CSR and B is dense; this op returns a dense C;

If transpose_output is false, returns:

C = A . B
 

If transpose_output is `true`, returns:

C = transpose(A . B) = transpose(B) . transpose(A)
 

where the transposition is performed along the two innermost (matrix) dimensions.

If conjugate_output is `true`, returns:

C = conjugate(A . B) = conjugate(A) . conjugate(B)
 

If both conjugate_output and transpose_output are `true`, returns:

C = conjugate(transpose(A . B)) = conjugate(transpose(B)) .
                                     conjugate(transpose(A))
