QVM: Quaternions, Vectors, Matrices


#include <boost/qvm/map_mat_vec.hpp>

namespace boost
    namespace qvm
        //Only enabled if:
        //  is_mat<A>::value &&
        //  mat_traits<A>::rows==mat_traits<A>::cols && mat_traits<A>::rows>=3
        template <class A>
        -unspecified-return-type- translation( A & a );

The expression translation(m) returns a view proxy that accesses the translation component of the square matrix m, which is a vector of size D-1, where D is the size of m.
