Next Combination/Permutation

Produces one comb/perm at a time. Both with/without repetition.

Description

The folder contains 4 files:

NEXTCHOOSE
NEXTMULTICHOOSE
NEXTPERM
NEXTSTRING

which correspond to the combinatorical problems:

Combinations without repetition.
Combinations with repetition.
Permutations without repetition.
Permutations with repetition.

Each of these will produce successive outputs of the combs/perms of K elements taken from the set 1:N.
See the screenshot for an example.

Please read the help before using.
Please email me if bugs are found, or improvements are found.

sorry there was a useless for. I use this

function [vector] = combine(n,k)
tc = factorial(n)/(factorial(k)*factorial(n-k));
vector = zeros(tc,k);
C = nextchoose(n,k);
for i=1:tc
        vector(i,[1:k]) = C();
end
