[Gretl-devel] Re: [EXTERNAL] Re: the choose() function
Hi Sven et al,
I’m still here, just haven’t been doing much gretl-related stuff lately :-(
Once everything’s finalized I’d be glad to update the matlab_utilities package to include
this functionality (which is very nice, btw).
Cheers,
Peter

Glad it's not going to be "choose"...

Would it be very difficult to add the faster algorithm?
About the Matlab name nchoosek: Not sure whether Peter Summers is still
around, but perhaps a nchoosek function could be added to his
matlab_utilities package which would be a thin wrapper around the native
bincoeff and the new combinations (or whatever name) functions.
cheers
