NCHOOSEK function

[Diego Ruiz Moreno]

Hi,
 Is there a equivalent to the NCHOOSEK matlab function in OCTAVE ?
 Here is the matlab description of the function (The interesting
functionallity 
if the second one)


 NCHOOSEK Binomial coefficient or all combinations.
    NCHOOSEK(N,K) where N and K are non-negative integers returns
N!/K!(N-K)!. 
This is the number of combinations of N things taken K at a time. When
a 
coefficient is greater than 10^15, a warning will be produced
indicating 
possible inexact results. In such cases, the result is good to 15
digits.
 
    NCHOOSEK(V,K) where V is a vector of length N, produces a matrix 
    with N!/K!(N-K)! rows and K columns. Each row of the result has K
of the 
elements in the vector V. This syntax is only practical for    
situations where 
N is less than about 15.

 Thanks

   D.
