W = nchoosecrit(S, FUN) returns those combinations of one or more element of the set S (called a subset) that fulfill a specific criterion. X can be any type of array. 1 5. matlab nchoosek vector. % combinator(4,2,'c','r') % Combinations with repetition 21 % combinator(4,2,'c') % Combinations without repetition 22 % 23 % 24 % If it is desired to use a set other than 1:N, simply use the output from 25 % COMBINATOR as an index into the set of interest. V can be any type of array (numbers, cells etc.) Learn more about permutation, without repetition ... assumes the result depends on order, i.e. MATLAB: How to compare each element of an array with the rest of the elements for several rows independently #nchoosek index matrix I want to compare each element of an array with the rest of the elements (in a single row of a matrix) and identify which pair(s) of indexes have both values of 1 (in each row). ' binom Binomial coefficient ufunc. all combinations of two elements
NCHOOSE2 - all combinations of two elements Y = NCHOOSE2(X) returns all combinations of two elements of the array X. Use bincoeff for non-integer and negative scalar arguments, or for computing many binomial coefficients at once with vector inputs for n or k.. See also: bincoeff, perms. See also. To build block arrays by forming the tensor product of the input with an array of ones, use kron.For example, to stack the row vector A = 1:3 four times vertically, you can use B = kron(A,ones(4,1)).. To create block arrays and perform a binary operation in a single pass, use bsxfun.In some cases, bsxfun provides a simpler and more memory efficient solution. : perms (v) Generate all permutations of v with one row per permutation.
