Is it okay if the source and destination overlap? For example, if I write A(3:5,1:3)=A(1:3,3:5), do I need to worry that maybe the new value of A(5,1) will be the old value of A(1,5) instead of the old value of A(3,3) (because maybe A(1,5) will be copied to A(3,3) and then A(3,3) will be copied to A(5,1))? I did a quick and simple test, and assignments like that seem to work, but I am still worried that it could be undefined behavior; maybe the result could be different in a future version of MATLAB.
