How to reverse a matrix dimension without affecting the other 2 (for 3 or more dimension matrixes)?

Hi,
I have a 3D matrix, let's say: A=rand(238,132,35). The problem is that the third dimension (the one with 35) is reversed and I need to turn it. It represents the depth in my case, and it needs to be not from 1 to 35 but from 35 to 1. And I need to do this without altering the other 2 dimensions. flipud obviously does not work for 3D matrix. Is there a flipud for 3D matrix? or any other way to do it?
Thanks,
Robert.

A = rand(238,132,35);
A = A(:,:,35:-1:1);
Or use flipdim (which basically does the above):
flipdim(A,3)
where the 3 stands for the 3rd dimension.
