Function shuffle¶

`function` shuffle(const vec<T, N> &, const vec<T, N> &, elements_t<Indices...>) simd ¶

template <size_t... Indices, typename T, size_t N, size_t count = sizeof...(Indices)>
KFR_INTRINSIC vec<T, N> shuffle(const vec<T, N>& x, const vec<T, N>& y,
                                elements_t<Indices...> i = elements_t<Indices...>())

Shuffles the concatenation of two equal-length vectors using a repeating index pattern.

The index pattern i is tiled to cover all N output lanes, with each tile offset by its tile index times count. The result is drawn from the concatenated sequence of x and y.

Template parameters
Indices	Compile-time index list defining the per-tile source selection.
T	Element type of the vectors.
N	Length of each input vector.
count	Number of indices in `Indices.`

Parameters
x	First source vector.
y	Second source vector.
i	Index pattern selector.

Returns
	A vector of length `N` drawn from the concatenated sequence.

Fully qualified name: kfr::shuffle(const vec<T, N> &, const vec<T, N> &, elements_t<Indices...>)
