I am trying to generate all possible combinations of 0,1,2 including repeats.
I have tried:
F = [0,1,2];
perms(F)
That works but it only gives the combinations with no repeats:
2 1 0
2 0 1
1 2 0
1 0 2
0 2 1
0 1 2
Including repeats there should be 27 combinations instead of just 6 without repeats

Ran in:
F = [0,1,2];
n_values = numel(F);
n_combos = n_values^n_values;
M = F(1+dec2base(0:n_combos-1,n_values)-'0');
disp(M);
0 0 0 0 0 1 0 0 2 0 1 0 0 1 1 0 1 2 0 2 0 0 2 1 0 2 2 1 0 0 1 0 1 1 0 2 1 1 0 1 1 1 1 1 2 1 2 0 1 2 1 1 2 2 2 0 0 2 0 1 2 0 2 2 1 0 2 1 1 2 1 2 2 2 0 2 2 1 2 2 2
