How can I compare individual rows of different matrices ?
Following code fails ;-(

typedef numerics::matrix< double > DMatrix;

DMatrix m (size, size);
for (int i = 0; i < m.size1 (); ++ i)
   for (int j = 0; j < m.size2 (); ++ j)
     m (i, j) = size * i + j;

DMatrix::matrix_row_type mr1 = m[1];
DMatrix::matrix_row_type mr2 = m[2];
std::cout << "equal ? " << ( mr1 == mr2 )<< std::endl;
