For example, for [1 2], [1 2] and [4 5] I want to generate the elements: [1 1 4; 1 1 5; 1 2 4; 1 2 5; 2 1 4; 2 1 5; 2 2 4; 2 2 5] The problem is that I don't know the number of vectors for which I need to calculate the combinations. I have an algorith that the number of possibles combinations of 0 and 1, can reach the number 2^39. 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 – … You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. and then check whether all(b <= a), but I was wondering if there is a smarter way to achieve this.

Learn more about combinations In regards to 'y' combinations of 'n' objects; is there any quick/easy way for excel to generate and display a list of all possible combination pairings or matchings? For example, a trivial case where a has only 4 elements. Its just a permutation of 3 numbers with repeatation. MATLAB: Show All Possible Combination and Max. Accelerating the pace of engineering and science. Description. Now, this could be done easily with some nested for loops, but that really does violate the spirit in which such challenges are issued. I am not sure how I can do recursion. Over at the SAS/IML Discussion Forum, someone posted an interesting question about how to create a special matrix that contains all combinations of zeros and ones for a given size.. PS: I have tried your first solution, but I suspect there is a bug, C = reshape(cat(l_word+1, C{:}), [], l_word), Modern Slavery Act Transparency Statement, You may receive emails, depending on your. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. We also make the current indices 0 in all the arrays to the right of this array. My colleague walked into my office with a MATLAB question, a regular pasttime for us here at the MathWorks. So the number of 1's in a must be small enough for this to be a practical approach. 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 But keep in mind that the memory requirements for this grows very quickly as the number of 1's in a increases. 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} . This algorithm (program in Matlab) calculates the number of permutations and combinations of … Description. Let's say i have n=2 situations, or n1=2^2=4 combinations of 0 and 1: 00,01,10,11.From that i can Learn more about combination, permutation MATLAB moves to the next element in that array. Description. This is not combination at all. . k!) 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? 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) -. 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. Unable to complete the action because of changes made to the page.

Learn more about mathematics, algorithm MATLAB and Simulink Student Suite In this example, we will use a simple polynomial function of degree 2 and will integrate it between the limits 0 to 4. Step 2: Use the integral function to calculate the integration. 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. The conditions of these possible combinations are no reputation of individual possibilities, and for each possible vector has the specified number of 1… We keep printing the combinations until no new combinations can be found. We will follow the following 2 steps: Step 1: Create the function of degree 2 in MATLAB. That's an extremely inefficient way of generating all permutations of length l of elements of a set of size n. For n = 2 and l = 20, you temporary generate 137,846,528,820 permutations when there are only 1,048,576 unique permutations.

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. I know the number of combinations should be 2^8 = 256. If you are using Windows, make sure to open MATLAB from the Start Menu or Explorer (do not open MATLAB from an OMNeT++ shell, as this changes environment variables that session sharing will rely on to work). Select a blank cell and type this formula =TEXT(ROW(A1)-1,"0000") into it, and press Enter key, then drag the autofill handle down until all the 4 digits combinations are listing. 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. I've tried dec2bin(0:(2^n)-1), but this only gives me all string combinations of length n, and I can't concatenate the strings of length 1 and 2 and so on because the dimensions do not match. Display the results in a three-column table in which each row corresponds to one triple.
