Detailed Description
template<class _Tp> class std::mask_array< _Tp >
Reference to selected subset of an array.
A mask_array is a reference to the actual elements of an array
specified by a bitmask in the form of an array of bool. The way to get
a mask_array is to call operator[](valarray<bool>) on a valarray. The
returned mask_array then permits carrying operations out on the
referenced subset of elements in the original valarray.
For example, if a mask_array is obtained using the array (false, true,
false, true) as an argument, the mask array has two elements referring
to array[1] and array[3] in the underlying array.
Parameters:
Tp Element type.
