Function Shuffle(a [, i])

Shuffle returns a random reordering (permutation) of the values in an array over index i. If you omit i [optional since build 4.0.0.48], it shuffles over Run. You may find this useful if you want to make a random sample from a probability distribution independent.

Declaration

Shuffle(a: Array[i]; i: IndexType = Run)

If a contains dimensions other than i, it independently shuffles each slice over those other dimensions.

If you want to shuffle the slices an array over index I, but leaving the values within each slice unshuffled, you can do this:

A[@I = Shuffle(@I,I)]

To make all slices of an uncertain result independent, use Shuffle(A), or equivalently, Shuffle(A,Run).
