Hi all,
I want to create a n*n matric from a 1*n matrix such that all possible every column is the shifted version of the previous one. For example, 1 2 3 4 then matrix should look like
1 2 3 4
2 3 4 1
3 4 1 2
4 1 2 3
Thanks

x = 1:4;
gallery('circul',x) %gallery strikes again!
More
fliplr(gallery('circul',fliplr(x)))
since you want it shifted to the left.

One way:
x = [1 2 3 4];
x = x(:);
x = repmat(x,1,4);
for nn = 2:4
x(:,nn) = circshift(x(:,nn),nn-1);
end
