ptr_mref

#include <boost/qvm/mat_traits_array.hpp>

namespace boost
{
    namespace qvm
    {
        template <int Rows,int Cols,class T>
        T (&ptr_mref( T * ptr ))[Rows][Cols];
    }
}

Returns:

A reference of type "array of Row arrays of Col elements of type T" to the memory pointed by ptr. This makes it possible to use the array at ptr as a matrix of size Row x Col.
