QVM: Quaternions, Vectors, Matrices

set_identity(mat)

#include <boost/qvm/mat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if:
        //  is_mat<A>::value &&
        //  mat_traits<A>::cols==mat_traits<A>::rows
        template <class A>
        void set_identity( A & a );
    }
}

Effects:

As if

assign(
    a,
    identity_mat<
        typename mat_traits<A>::scalar_type,
        mat_traits<A>::rows,
        mat_traits<A>::cols>());
