Hi, and thank you in advance for taking the time to read this. Is there a quick way to get all possible pairs from a vector? For example A=[1 2 3 4 5]; [1 2], [1 3], [1 4], [1 5], [2 3], [2 4], [2 5], [3 4], [3 5], [4 5]. I think I can get that with 2 for loops but I would like to know if there's a know faction for that.
Thank you

Try this:
A = [1 2 3 4 5];
Out = nchoosek(A, 2)
Out =
1 2
1 3
1 4
1 5
2 3
2 4
2 5
3 4
3 5
4 5
