class std::valarray< _Tp >"
Smart array designed to support numeric processing\&. 

A valarray is an array that provides constraints intended to allow for effective optimization of numeric array processing by reducing the aliasing that can result from pointer representations\&. It represents a one-dimensional array from which different multidimensional subsets can be accessed and modified\&.
