Hi,

I am using nchoosek(n,k) to generate the number of combinations
n!/(k!(n-k)!).
Unfortunately, it seems there is no vectorized version, for n and k are
vectors or matrices of the same size.

I don't want to generate the actual combinations, which is what nchoosek()
does if you start using vectors.  Did matlab decided to use the same
function for two different things?  Seems like a bad idea to me. I hate to
iterate through the matrices myself... :(

Thanks,
-Frank
