Detailed Description

template<typename _Tp>
class std::slice_array< _Tp >

Reference to one-dimensional subset of an array.

A slice_array is a reference to the actual elements of an array specified by a slice. The way to get a slice_array is to call operator[](slice) on a valarray. The returned slice_array then permits carrying operations out on the referenced subset of elements in the original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this slice_array refers to.

Parameters:

Tp	Element type.
