hi,

i'm trying to understand the different forms of assignments in boost
ublas (a) and b)). some help would be appreciated.

        // Assignment
a)        BOOST_UBLAS_INLINE
        vector_range &operator = (const vector_range &vr) {
            vector_assign<scalar_assign> (*this, typename
vector_temporary_traits<V>::type (vr));
            return *this;
        }
b)        BOOST_UBLAS_INLINE
        vector_range &assign_temporary (vector_range &vr) {
            // assign elements, proxied container remains the same
            vector_assign<scalar_assign> (*this, vr);
            return *this;
        }
