Hello,
I have 4 vectors A B C D of 100 x 1 matrix of data each.

I'm trying to pair them up in loop in unique combinations.
ie.

A = rand(100,1);
B = rand(100,1);
C = rand(100,1);
D = rand(100,1);
pair = 2;
for x = 2

combo1 = [A B];
combo2 = [A C];
combo3 = [A D];
combo4 = [B C];
combo5 = [B D];
combo6 = [C D];

end

As you can all see, I'm doing this manually. Is there a way to code a logic so this gets done in a loop and also a condition so that [A B] won't get repeated as [B A] since thats essentially the same pairwise.


Thanks,
ben
