I can't see how you would do this without at least the size() command. You need that to determine the size of your loops.
Anyway, because this is homework, I will just give an example similar to what you are asking. Below is code to transpose a matrix purely with loops. I leave it to you to modify it as needed for a 90 degree rotation.
[m,n]=size(A);
for i=m:-1:n
for j=n:-1:1
B(j,i)=A(i,j);
end
end
