Details:

circshift in ML supports the following calling syntax:


Y = circshift(X,K,DIM) circularly shifts along the dimension DIM.


where X is the matrix, K is a scalar integer and DIM is the dimension in which
to shift. Octave does not support it. It could probably be added by just
adding a recursive call to circshift like:


if (nargin == 3)
  if isscalar (n)
    k = zeros (1,dim);
    k(dim) = n;
    y = circshift (x,k);
    return;
  else
    error ("n must be a scalar if calling circshift with three arguments.");
  endif
endif
