Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

QVM: Quaternions, Vectors, Matrices

set_zero(vec)

#include <boost/qvm/vec_operations.hpp>

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

Effects:

As if

assign(a,
    zero_vec<
        typename vec_traits<A>::scalar_type,
        vec_traits<A>::dim>());
