MATLAB: How to avoid repeat numbers in a row

Question

Dear All,

I have this row

A=[1 2 3 4 5 6];

I tried to find random permutation on the vector but in many cases I got a row with repetition numbers for example

    z=[1 5 2 4 1 5];or z=[1 5 2 4 1 1];

I want to avoid the repetition in this code but it is totally wrong, at first I should assign the missing numbers in such way, here is [3 6].

zc=[3 6 ];
 e=size(zc,2);
   z=[1 5 2 4 1 5];
for i=1:6
    z(i)==z
  s = find((z(i)==z) == 1)
 ss=size(s,2);
 for j=2:ss  
   for   k=1:e
      z(j)=zc(k)
      end
    end
end

I don't want to use a function from matlab to get the permutation, I need to fix my row or any permutation exchange file like (perm file ). If anyone help me for it and save me I will be grateful.

regards,

Imola

Answer 1

[~,x] = sort(rand(1,6))

No randperm
