## Detailed Description

### template<class V>
class boost::numeric::ublas::vector_range< V >

A vector range can be used as a normal vector in any expression. If the specified range falls outside that of the index range of the vector, then the `vector_range` is not a well formed Vector Expression and access to an element outside of index range of the vector is undefined.

Template Parameters:

  | V | the type of vector referenced (for example `vector<double>`)
