Almost, but not quite.  At least not if he wants *exactly* what's
written above.  Then he wants

        [z(:), x(:), y(:)]

or, for that matter, any of the following

      * shift ([x(:), y(:), z(:)], 1, 2)
      * circshift ([x(:), y(:), z(:)], [0, 1])
      * [x(:), y(:), z(:)] (:, [3, 1, 2])

What other alternatives are there?
