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

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

[edit] Template parameters

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

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