Defined in header <experimental/simd>
template < class M, class V >
class where_expression;
(parallelism TS v2)

The class template where_expression abstracts the notion of selected elements of a given non-const object of arithmetic or data-parallel type. Selected elements signifies the elements data[i] for all i ∈ {j ∈ ℕ0 | j < M::size() ⋀ mask[j]}.

Template parameters

M - The mask type
V - The value type M applies on

Valid combinations of (M, V) are: (simd_mask<T, Abi>, simd<T, Abi>), (simd_mask<T, Abi>, simd_mask<T, Abi>), (bool, T).

Member functions

(public member function)
compound operators
(public member function)
increment and decrement operators

loads from address to selected positions
