>> syms x y z u
>> A = [x y; z u];
>> A =
         [x    y]
         [      ]
         [z    u]
>> B = permute(A, [2 1]);
>> B =
         [x    y]
         [      ]
         [z    u]
However
>> B = A.'

works.

This is a problem for multidimensional symbolic arrays.

I know for a fact that permute works correctly with Matlab 2007b since I use both versions simultaneously.

What gives?

Ah, I knew I'd see this before somewhere.
