cpp/experimental/simd/where expression

The class template abstracts the notion of selected elements of a given lvalue of arithmetic or data-parallel type. Selected elements are the elements of the lvalue (of type ) for which the corresponding element of the mask (of type ) is true. Operators applied to objects of type are applied only to selected elements. All other elements are left unchanged.

Use the function to construct  objects.
