What do you mean by "diagonally rotated" -- do you mean
"tranposed"? If you want to tranpose the array, you probably want

permute(x, [2, 1, 3])

which is the 3D special case of the ND-case

permute(x, [2, 1, 3:ndims(x)])


I wish dialog boxes had a button saying "Whatever". I hate being
forced to answer "Yes" or "No" to a question I have no opinion on
whatsoever. There ought to be a button matching my indifference.
