% Below is the code to rotate by 90 but how to rotate a matrix by 180 and 270
A=[1 2 3 4;5 6 7 8;10 11 12 13]
[nr,nc] = size(A);
At = zeros(nc,nr);
for i = 1:nr
for j = 1:nc
At(j,i) = A(i,j); end end
disp(At)

No, the code you've posted will transpose A, not rotate it by 90 degrees. Compare
>> At, rot90(A)
At =
1 5 10
2 6 11
3 7 12
4 8 13
ans =
4 8 13
3 7 12
2 6 11
1 5 10
Since the code you've posted is also code that I gave you in another thread as a homework hint, I will now close this thread.
