thank you about your answer but i think with this example i can explain it more . The command perms([2 4 6]) returns all the permutations of the numbers 2, 4, and 6:

     6     4     2
     6     2     4
     4     6     2
     4     2     6
     2     4     6
     2     6     4

perms returns all permutation of numbers,but i want combination such as 6 6 6 and 4 4 4 and 2 2 2 too.Am i supposed to program it by my self?
