Hi Andy, the relevant tests for sparse matrices times dense matrices are in tests/spmdm.cpp. In particular, I recreated a test case based on your description and couldn't find any issues:
viennacl::compressed_matrix<NumericT> compressed_A; viennacl::matrix<NumericT, FactorLayoutT> B1(std_A.size(), cols_rhs); viennacl::matrix_base<NumericT> B1_ref(B1); viennacl::matrix_base<NumericT> C2(viennacl::linalg::prod(compressed_A, B1_ref)); compiles cleanly. Could you please provide a code snippet demonstrating the problem you are encountering?
