Generate nchoosek vectors line-by-line

I would like to interate through combinations according to the code,

combos = nchoosek(1:512,6);
for c = 1:size(combos,1)
    % code
end

However, the number of combinations, 2.4295e+13, is too big. Is there a way to generate the combinations line-by-line? I have no intention of running code for every single one, but I would like to index and get a specific combination for that index.

There are loads of nchoosek functions available on the file exchange: nchoosek. Some of those should help you with this. I recall using versions by Jos, Bruno Luong, or/and Jan.
