Unfortunately, it seems there is no vectorized version, for n and k are
vectors or matrices of the same size.

It looks like bincoeff(N,k) does what you want.
bincoeff( reshape( [10:2:20]', 3, 2 ), reshape( [5:10]', 3, 2 ) )
ans =
252 12870
924 48620
3432 184756
Should we do away with nchoosek()? Alias it to bincoeff()?
