MATLAB: All combinations from a set of rows without repetition of elements. Read More. Best Answer. Number of combinations n=11, k=3 is 165 - calculation result using a combinatorial calculator. I want to find all the possible combinations from a set of pairs. COMBINATIONS WITHOUT REPETITION/REPLACEMENT COMBINATOR(N,K,'c') -- N >= 1, N >= K >= 0. Say I have this line of code: c=nchoosek(1:6,2) , it gives: permutation without repetition. combos = combntns(set,subset) returns a matrix whose rows are the various combinations that can be taken of the elements of the vector set of length subset.Many combinatorial applications can make use of a vector 1:n for the input set to return generalized, indexed combination subsets.. Combinatorial Calculator. Example: combinator(4,2,'p','r') % Permutations with repetition ... For Matlab 7.8, this is about 30% faster than the original subroutine perms_loop. Oct 19, 20 06:17 AM. Description. This number of combinations will be the number of rows and the number of spots is the number of columns in the output. Taking 5 at a time. Data contains 171 values, and all of the combinations without replacement would probably be some milions, whereas I basically only need around 1000 combinations without replacement.. where n = 7 for my purposes and r is a changeable number of spots as I called it.
