Function permute¶

`function` permute(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> permute(const vec<T, N>& x, elements_t<Indices...> i = elements_t<Indices...>())

Permutes the lanes of x 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.

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

Parameters
x	Source vector.
i	Index pattern selector.

Returns
	A vector of length `N` with lanes permuted according to `i.`

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