row_mat

#include <boost/qvm/map_vec_mat.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_vec<A>::value
        template <iclass A>
        -unspecified-return-type- row_mat( A & a );
    }
}

The expression row_mat(v) returns a view proxy that accesses the vector v as a row matrix.
