# boost::numeric::ublas::zero_vector< T, ALLOC > Class Template Reference

A zero vector of type `T` and a given `size` A zero vector of type `T` and a given `size`. This is a virtual vector in the sense that no memory is allocated for storing the zero values: it still acts like any other vector. However assigning values to it will not change the zero vector into a normal vector. It must first be assigned to another normal vector by any suitable means. Its memory footprint is constant.
