Constructor & Destructor Documentation

Eigen_matrix()

template<class FT , int D1 = ::Eigen::Dynamic, int D2 = ::Eigen::Dynamic>

CGAL::Eigen_matrix< FT, D1, D2 >::Eigen_matrix	(	std::size_t	nr,
		std::size_t	nc
	)

Constructs an uninitialized matrix with nr rows and nc columns.

This is useful for dynamic-size matrices. For fixed-size matrices, it is redundant to pass these parameters.
