`function` odd(const vec<T, N> &) simd ¶

template <size_t group = 1, typename T, size_t N, size_t Nout = N / 2>
    requires(N >= 2 && (N & 1) == 0)
KFR_INTRINSIC vec<T, Nout> odd(const vec<T, N>& x)

Extracts the odd-indexed elements of x (with optional grouping).

Elements at indices group, 3* group, 5* group, ... are gathered into the result.

Template parameters
group	Stride between consecutive selected pairs.
T	Element type of the vector.
N	Input vector length, must be even and at least 2.
Nout	Output length, defaults to `N` / 2.

Parameters
x	Source vector.

Returns
	A vector of length `Nout` holding the odd-indexed elements of `x.`

Fully qualified name: kfr::odd(const vec<T, N> &)
