scalar_cast(mat)

#include <boost/qvm/mat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_mat<A>::value
        template <class Scalar,class A>
        -unspecified-return_type- scalar_cast( A const & a );
    }
}

Returns:

A read-only view proxy of a that looks like a matrix of the same dimensions as a, but with scalar_type Scalar and elements constructed from the corresponding elements of a.
