Start Hunting! Accepted Answer: Matt Fig. 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) The issue I'm having is that if I use combvec() then I have to hardcode the vectors into it, which doesn't work for if there are more than 2 vectors. to avoid repeat combinations in the form of [20 30; 30 20], And to remove self-combinations such as [20 20]. all possible combinations of three vectors.

There is a function called combnk that will enumerate combinations for you. MATLAB: All possible combinations of vectors of unknown quantity and length. The most hokey way I can think of is to have one loop and then have counts for how many times I have used each vector to build the combinations. I want to obtain all possible combinations of a set of vectors. combinations for loop MATLAB. I would like an "easy" way to get all the possible combinations of n pairs of 2 elements (one from each vector) without repeating any element, and place them in … He wanted to take every combination of one value from each of three distinct vectors.
