This MATLAB function takes any number of inputs, Matrix of N1 (column) vectors Matrix of N2 (column) vectors . The new cell array has to be of length 6 cells (number of possible combinations), and each cell has a possible combinations, for example A{1}={1 2 3 4 and -1 -2 9} and A{2}={1 2 3 4 and 0 9 6} . all posible combinations of 0 and 1. array: [-1 -1 2] desired sum: [2] so my ecuation would look like this: -x-y+2z=2 output: result:[-1 1 1] How can this be done in Matlab? Note that at no point will the above generate a combination where b > a to later discard it, so it's going to be a lot more efficient than your prospective loop. all combinations of numbers. For example, a trivial case where a has only 4 elements. If taken 3 at a time the combination will be 123 and if taken 1 at a time the combination will be 1,2 and 3. so the total combination will be 1,2,3,12,13,23,123. Display the results in a three-column table in which each row corresponds to one triple. Find the treasures in MATLAB Central and discover how the community can help you! Reload the page to see its updated state. You may receive emails, depending on your. Seems good to me,except the typo on first line (2^N-1 instead of 2^N²-1).Plus I'd point out that this approach doesn't force you to store all of these combinations in memory, as it gives a 1:1 correspondance between your matrices and 0:2^N²-1, meaning if you just need to get one of these matrices at random for example, you can just pick a number and then apply the equivalence – … So the number of 1's in a must be small enough for this to be a practical approach. Ex. Let's say I have A = [2 5 8] and B=[1 4]. The combntns function provides the combinatorial subsets of a set of numbers.

MATLAB: All combinations of two elements from a 3 by 7 matrix without repeating from the same column. I could easily write a loop that starts filling zero 1's, then continues with filling one 1's, two 1's, etc. Starting from the rightmost array we check if more elements are there in that array. Generate all combinations of the elements of x taken m at a time. We also make the current indices 0 in all the arrays to the right of this array. Two better ways of generating the same without any extra work: C = reshape(cat(n_letters, C{:}), [], l_word), C = dec2base(0:n_letters^l_word - 1, n_letters) -. Now, this could be done easily with some nested for loops, but that really does violate the spirit in which such challenges are issued. How to find the (x,y) combinations that make z=0? I have a vector of 0's and 1's, say a, and I want to find all possible vectors B of 0's and 1's for which b <= a, for all b in B. We will follow the following 2 steps: Step 1: Create the function of degree 2 in MATLAB. Let's assume you need a vector of l_word = 4 elements, each of them can be a 0 or a 1. s = repmat((0:n_letters - 1), 1, l_word); C is a matrix of all words of length 4 you can build using letters 0 and 1. For example if I had a martix. Hello, I'd like to create all possible combinations of two elements from a 3 by 7 matrix without repeating elements from the same column. all combinations is working nice however when i type 26 and 5 were you comment to one of the users is giving me all the combinations from 1 to 26 but i need for certain numbers and how much i tried i just could'nt modify the code to fit my purpose Open MATLAB. all possible combinations are needed in my situation.
