The following code is not working for me:
---------------------------------------
using namespace boost::numeric::ublas;
matrix<double> m (3, 3);
matrix<double> o (3, 3);
for (unsigned i = 0; i < m.size1 (); ++ i)
for (unsigned j = 0; j < m.size2 (); ++ j)
{
m (i, j) = 3 * i + j;
o (i, j) = 3 * i + j;
}
std::cout << m << o << std::endl;
matrix_vector_binary2< matrix_row< matrix<double> >, matrix<double>, double >
D;
D = prod(row(m, 1),o);
---------------------------------------
the error is
