Rotation of a Volume

Sorry about this simple question but didn't find a way of doing it.

Is there a way I can do the following

for i=1:nslices
    A(:,:,i)=rot90(A(:,:,i),3);
end

without having the loop? The loop takes a while.

In general what I'm doing is rotating a volume about the third dimension

imrotate(A,90*3) will do it if you have the appropriate toolbox.

You can also do things like this

A = flipdim(permute(A,[2,1,3]),2);
