Function insertlow¶

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

template <typename T, size_t N>
KFR_INTRINSIC vec<T, N> insertlow(T x, const vec<T, N>& y)

Inserts a scalar x at the low (left) end of y, shifting y one lane to the high (right) side.

The highest lane of y (index N-1) is discarded; x occupies the lowest lane. Given y = [y0, y1, ..., y(N-1)], the result is [x, y0, ..., y(N-2)].

Template parameters
T	Element type of the vector.
N	Input vector length.

Parameters
x	Scalar value to insert at the low end.
y	Source vector.

Returns
	A vector of length `N` with `x` at lane 0 and `y` shifted right by one.

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