Shift a column circularly in a for loop

Hi, I want to shift a column vector (fullmat) circularly, and append to the column vector each time the new column. I want to do this, shifting by 1 each time, several times (101 times) in a for loop. But my code does not seem to work very well.

y5=rand(1,101);
fullmat=y5.';
for idx=1:101
    circ = circshift(y5,idx,1);
    fullmat= [fullmat; circ];
end

[numnum]

nervermind, i got it!
