Detailed Description

template<class _Tp>
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.

Template Parameters
_TpType of object in the array.
