I'm not sure that this is what the OP really wants, but this works in

  tmp(1,1,1,:) = 1:3;
  r = repmat (tmp, [3,3,3])

you can use any dimensions, not just [3,3,3] here.

Ooh, is that a new feature of repmat in 2.9.10? The documentation in
2.9.9 seems to imply that repmat only works on matrices, not N-d
arrays. Hm, once Debian devs fix the problems with the 'forge and the
2.9.10 packages, I'll upgrade.
