a= [ 3 4 5; 7 8 9; 3 6 8 ; 4 6 9; 3 6 5]
I expected the answer is
b=
[ (3,4) (4,3)
(4,5) (5,4)
(7,8) (8,7)
(8,9) (9,8)
(3,6) (6,3)
(6,8) (8,6)
(4,6) (6,4)
(6,9) (9,6)
(3,6) (6,3)
(6,5) (5,6)

Maybe you ask for this:
D = reshape([a.' circshift(a.',-1)], [], 2);
D(size(a,2):size(a,2):end,:)=[];
out =[D fliplr(D)]
