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\&.
.PP
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\&.
