Script that create all combination in a matrix

Hello,

I have a matrix of 3 elements (3 columns).

A | B | C

Each elements can take 4 values (0, 1, 2, 3). Is there a function or a way to test all possibilities and complete the matrix with all possibilities ? So 3^4 possibilities.

0|1|2

0|1|3

...

...

Thanks

Edit : I miss an information, in my case elements can have same values so i need to take in consideration :

0 | 0 | 0

1 | 1 | 1

0 | 0 | 2

Thanks it works for all differents values combination ! But is there also a way to generate combination when elements can have same values too like the in the edit of the post ?

Yet another possible solution:

A=0:3;B=0:3;C=0:3;
[A_,B_,C_]=ndgrid(A,B,C);
combs=[A_(:),B_(:),C_(:)];
