MATLAB: Ordering a list of number

MATLAB

let say i have 6 different number(J) 1,2,3,4,5,6, how can i use matlab to arrange all possible oder? eg 2,1,3,4,5,6 . 1,2,4,3,5,6 etc?

doc perms

Gives all the permutations of the vector

c=[1,2,3,4,5,6]
perms(c)

sortrows(I,-1)

combvec() from the Deep learning toolbox is most easiest solution

a = [1 2 3]
b = [1 2 3]
C = combvec(a, b).'; % if the order of column is important: C = fliplr(combvec(a, b).');

The other solution is to use ndgrid()

a = [1 2 3]
b = [1 2 3]
[A, B] = ndgrid(a, b);
C = [B(:) A(:)]
