MATLAB Query !!!!!!

Question

How can I able to make different combinations of the set { 1 2 3 4 } where any one digit from the set can repeat more than one time in that particular combination using MATLAB inbuilt function
OR
I should make my own algorithm for this ??????
Example :
1. Input : { 1 2 3 4 }
2. Output : 1 1 1 1
1 1 1 2
1 1 1 3
1 1 1 4
1 1 2 3
1 1 3 4
1 1 2 4
1 2 3 4 and so..

Answer 1

Hey, if you want to do permutations you have to do this:
for example:
v=[1 2 3 4];
P= perms (v)
