NAME¶

std::experimental::where_expression - std::experimental::where_expression

Synopsis¶

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

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