Boost QVM

set_rotz(m,s)

namespace qvm
{
    //Only enabled if:
    //  is_m<A>::value && m_traits<A>::rows>=3 &&
    //  m_traits<A>::rows==m_traits<A>::cols
    template <class A>
    void set_rotz( A & a, typename m_traits<A>::scalar_type angle );
}

Effects:

As if:

assign(a,rotz_m<m_traits<A>::rows>(angle));
