ONECOMB

Obtain a single combination of N numbers taken K at a time.

comb = ONECOMB(N,K,M) returns the M-th combination of the sorted list of all combinations from NCHOOSEK.
Makes use of a fast algorithm for the generation of a single combination.

NCHOOSEK(1:4,3) =
[ 1 2 3
1 2 4
1 3 4
2 3 4 ]

onecomb(4,3,3) =
[ 1 3 4 ]
