Hi Andrew, > I'm having some trouble with sparse `compressed_matrix` `matrix`(base) > matrix multiplication. This is supported, correct?
Yes. Could you please let us know what you have tried already? It shouldn't be any more code to write than viennacl::compressed_matrix<T> A(...); viennacl::matrix<T> B(...); viennacl::matrix<T> C = viennacl::linalg::prod(A, B); Make sure to #include "viennacl/matrix.hpp" #include "viennacl/compressed_matrix.hpp" #include "viennacl/linalg/prod.hpp" at the beginning; otherwise you get incomprehensible C++ compiler output.
