std::experimental::where_expression

Template:cpp/experimental/simd/where expression/navbar content

 

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

operator=	assigns to selected positions (public member function)
operator+= operator-= operator*= operator/= operator%= operator&= operator|= operator^= operator<<= operator>>=	compound operators (public member function)
operator++ operator--	increment and decrement operators (public member function)
copy_from	loads from address to selected positions (public member function)
