Returns element 2,1 from a matrix (used to test copy/nocopy)

// Returns element 2,1 from a matrix (used to test copy/nocopy)
double get_elem(const Eigen::Ref<const Eigen::MatrixXd> &m) { return m(2, 1); }

// Returns a matrix with 10*r + 100*c added to each matrix element (to help test that the matrix
// reference is referencing rows/columns correctly).
