QVM: Quaternions, Vectors, Matrices

operator*=(quat,quat)

#include <boost/qvm/quat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if:
        //  is_quat<A>::value && is_quat<B>::value
        template <class A,class B>
        A & operator*=( A & a, B const & b );
    }
}

Effects:

As if:

A tmp(a);
a = tmp * b;
return a;
