MATLAB: Error for function permutation with repetition.

permutation with repetitionundefined function or variable 'permn'

Dear all,

I am using matlab 2016b and try to find al the permutations with repetition. But it gives me an error saying: Undefined function or variable 'permn'.

So I wonder, what is missing in is my code is there another function/code needed for my version of matlab?

This is the code:

%Find all possible prob
I=0:200;
M = permn(I,3);

Can I have some feedback please?

Thank you in advance

MATLAB: Find missing element between two matrix

>> A = [1,2;3,6;3,5;1,4;4,6;2,7;1,6;6,5;2,3;6,7;3,4];
>> B = [1,2;1,6;2,3;3,4;4,6];
>> R = setdiff(A,B,'rows')
R =
   1   4
   2   7
   3   5
   3   6
   6   5
   6   7

To get the same order, use the 'stable' option or this:

>> [~,X] = setdiff(A,B,'rows');
>> X = sort(X);
>> R = A(X,:)
R =
   3   6
   3   5
   1   4
   2   7
   6   5
   6   7
