Detailed Description

template<typename Type>
class std::gslice_array< Type >

Reference to multi-dimensional subset of an array.

A gslice_array is a reference to the actual elements of an array specified by a gslice. The way to get a gslice_array is to call operator[](gslice) on a valarray. The returned gslice_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 gslice_array refers to.

Parameters:
Tp Element type.
