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

A scalar (i.e. unique value) vector of type `T` and a given `size` A scalar (i.e. unique value) vector of type `T` and a given `size`. This is a virtual vector in the sense that no memory is allocated for storing the unique value more than once: it still acts like any other vector. However assigning a new value will change all the value at once. vector into a normal vector. It must first be assigned to another normal vector by any suitable means. Its memory footprint is constant. More...

## Detailed Description

### template<class T, class ALLOC>
class boost::numeric::ublas::scalar_vector< T, ALLOC >

Template Parameters:

  | T | type of the objects stored in the vector: it can be anything even if most of the time, scalar types will be used like `double` or `int`. Complex types can be used, or even classes like boost::interval.
