function digitreverse(const vec<T, N> &) shuffle¶

template <size_t radix, size_t group = 1, typename T, size_t N>
KFR_INTRINSIC vec<T, N> digitreverse(const vec<T, N>& x)

Reorders the elements of a vector by reversing the digits of their indices in the specified radix.

Optionally groups elements before reversing.

Template parameters

radix	The numeric base used for digit reversal (2 or 4).
group	The grouping size; elements are grouped before index reversal.
T	The element type of the vector.
N	The number of elements in the vector.

Parameters

x	The input vector to be reordered.

Returns

A vector with elements reordered based on digit-reversed indices.
