# QVM: Quaternions, Vectors, Matrices

### set_rotx(quat,scalar)

#include <boost/qvm/quat_operations.hpp>

    namespace qvm
    {
        //Only enabled if: is_quat<A>::value
        template <class A>
        void set_rotx( A & a, typename quat_traits<A>::scalar_type angle );
    }

#### Effects:

As if:

    assign(
        a,
        rotx_quat(angle));
