The problem is that Example(:,:,2) is a 2-dimensional array, so calling 
permute with 3 dimensions returns an error. On the other hand,
permute(Example, [2 3 1])
permute(Example(:,:,2), [2 1])

are both valid usages of permute. Note that permute(Example(:,:,2), [2 
1]) is equivalent to Example(:,:,2)', the transpose.

Quentin
