Detailed Description

template<class Type>
class std::indirect_array< Type >

Reference to arbitrary subset of an array.

An indirect_array is a reference to the actual elements of an array specified by an ordered array of indices. The way to get an indirect_array is to call operator[](valarray<size_t>) on a valarray. The returned indirect_array then permits carrying operations out on the referenced subset of elements in the original valarray.

For example, if an indirect_array is obtained using the array (4,2,0) as an argument, and then assigned to an array containing (1,2,3), then the underlying array will have array[0]==3, array[2]==2, and array[4]==1.

Parameters:
Tp Element type.
