how to arrange vector to matrix?

Hi guys,

I have a vector: x = [1 2 3 4 5 6]

How to arrange this vector to new matrix, like this:

[1 2 3 4 5 6

2 3 4 5 6 1

3 4 5 6 1 2

4 5 6 1 2 3]

Thanks for your help.

x = [1,2,3,4,5,6];
m = hankel(x(1:4),x([4:6,1:3]))

m = 4×6

1 2 3 4 5 6 2 3 4 5 6 1 3 4 5 6 1 2 4 5 6 1 2 3

You can try using the functions perms. or if you want cyclic permutations

x=[1,2,3,4,5,6];
v=perms(x)

v = 720×6

6 5 4 3 2 1 6 5 4 3 1 2 6 5 4 2 3 1 6 5 4 2 1 3 6 5 4 1 3 2 6 5 4 1 2 3 6 5 3 4 2 1 6 5 3 4 1 2 6 5 3 2 4 1 6 5 3 2 1 4

X=[1,2,3,4,5,6];
V=[X;circshift(X,1);circshift(X,2);circshift(X,3);circshift(X,4);circshift(X,5);]

V = 6×6

1 2 3 4 5 6 6 1 2 3 4 5 5 6 1 2 3 4 4 5 6 1 2 3 3 4 5 6 1 2 2 3 4 5 6 1
