n permute k

version 1.1 (2.36 KB) by

Based on Matt Fig's npermutek this function returns all possible permutations of most matlab classes

Permutation of elements with replacement/repetition. MAT = npermutek(N,K) returns all possible samplings of length K from vector N of type: ordered sample with replacement. MAT has size (numel(N)^K)-by-K, where K must be a scalar. [MAT, IDX] = npermutek(N,K) also returns IDX such that MAT = N(IDX).
  N may be of any numeric class, char, cell, struct, or even obj.

Finally a combinatorics submission that actually recognizes the difference between combinations and permutations!
