Function shufflegroups¶

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

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

Group-wise variant of shuffle() that operates on blocks of group elements.

Same as shuffle() but the index pattern is applied per group of group consecutive lanes rather than per single lane.

Template parameters
group	Number of lanes in each group.
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, shuffled by group.

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