# QVM: Quaternions, Vectors, Matrices

### set_identity(quat)

#include <boost/qvm/quat_operations.hpp>

    namespace boost
    {
        namespace qvm
        {
            //Only enabled if: is_quat<A>::value
            template <class A>
            void set_identity( A & a );
        }
    }

#### Effects:

As if

    assign(
        a,
        identity_quat<typename quat_traits<A>::scalar_type>());
