operator-=(mat,mat)

#include <boost/qvm/mat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if:
        //  is_mat<A>::value && is_mat<B>::value &&
        //  mat_traits<A>::rows==mat_traits<B>::rows &&
        //  mat_traits<A>::cols==mat_traits<B>::cols
        template <class A,class B>
        A & operator-=( A & a, B const & b );
    }
}

Effects:

Subtracts the elements of b from the corresponding elements of a.

Returns:

a.
