Binomial coefficient or all combinations . However, I'm not sure that's what you are asking since you've included [1 1 1] as a possible combination of [1 2 3] - I have no idea how [1 1 1] is a combination of [1 2 3] (though by extension of that logic, I'm not sure why you don't include [2 2 2] and [3 3 3] in your list, as well as numerous other things if you're going to repeat elements) combinations for loop MATLAB. 1 ⋮ Vote. This worked for me (probably the same thing that's going on in the "ALLCOMB" function that was suggested): combinations = cellfun(@(x) x(:), combinations.
