Hello, I've been searching for a function that give all permutations of c elements in n, as "combnk" Matlab function. I fund in this forum http://octave.1599824.n4.nabble.com/combinations-td1636272.html a solution using "perms" function. However, "perms" function sets a matrix of prod(2:n) line, which limits the use to n=10;
I tried an empiric algorithme, that can replace the use of "unique(sort (perms (1:n)(:,1:c), 2), 'rows')" I am not a mathematician, and not even a programmer, but this code may inspire someone for a "clean" code. Martin
