Matrix Permutation to generate another Matrix

Hello,

I have matrix v. I used p = perms(v) to produce results p. P goes on and on for a ways. I just shared a snip of what it is doing.

What would be the way to do this so I would get the results shown below? The order cannot change. Like you cant swap column 1 and 2. Would it be better to randamize each column instead? Thanks!

p =

2 6

2 3

2 5

1 6

13

15

7 6

7 3

7 5

  v = [2 6; 1 3; 7 5]

v = 3×2

2 6 1 3 7 5

  [t1, t2] = ndgrid(v(:,1), v(:,2));
  p = [t1(:), t2(:)];
  
  p

p = 9×2

2 6 1 6 7 6 2 3 1 3 7 3 2 5 1 5 7 5
