Is there a way to combine two variables?

I want combine two variables so that I can use it with the command 'patch' to create multiple rectangles which apparently has to have a matrix of x by 2 for each coordinate. So essentially what I want to do is this (this isn't the actual code I have, it's just visually what I want to happen if it's possible):

A=1 2 3 4     B= 8 7 6 5
  5 6 7 8        4 3 2 1
  
  AB= (1 8)
      (2 7)
      (3 6)
      (4 5)
      (5 4)
      (6 3)
      (7 2)
      (8 1)

Is it possible to do that and then convert it into a matrix so it's useable by 'patch'?

If the order in AB is not critical, as long as elements of A are matched with elements of B:

AB = [A(:), B(:)];

If you absolutely need to have the order you specify:

AB = [reshape(A.', [], 1), reshape(B.', [], 1)];
