Details:

octave-3.2.4.exe:10> bincoeff(100,10)
ans =  17310309456441

The correct result is:

octave-3.2.4.exe:13> 10*11*98*97*19*31*23*13*94
ans =  17310309456440

Matlab gives the correct result with nchoosek(100,10).
Maybe bincoeff can be improved for large input?

Best regards and thanks
Marcus
