Hi all, I.m trying to transform vector A into B as below,
A B
[ 1 2 3 4 ] [ 4 1 2 3 ]
Here is what I have got so far, but it didnt work out, please point out where I got it wrong
A = [1 2 3 4];
B = [A(1)];
for i = [2:length(A)]
B = [A(i) B]
end
disp(B);

Ran in:
A=[ 1 2 3 4 ];
B=[A(end),A(1:end-1)]
B = 1×4
4 1 2 3

circshift(a, 1)

thank you, but do you have a simpler version of it?
I'm trying to figure out what I got wrong rather than using a new operator
