Just adding my opinion here as I have been following this thread. Would it be possible to have both the .so library and header only options available or is it a strictly 'this-or-that' scenario? Regards, Charles On Wed, Aug 17, 2016 at 2:53 PM, Karl Rupp wrote: > Hi Dmitriy, > > > We could

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 compressed_A; viennacl::matrix B1(std_A.size(), cols_rhs); viennacl::mat
