Follow-up Comment #7, bug #39636 (project octave):

Thanks for your help with this issue.  I believe the R statistical software
might be helpful.

http://stat.ethz.ch/R-manual/R-patched/library/stats/html/NegBinomial.html

Following the source code, I see:

http://svn.r-project.org/R/trunk/src/nmath/pnbinom.c

http://svn.r-project.org/R/trunk/src/nmath/pbeta.c

http://svn.r-project.org/R/trunk/src/nmath/toms708.c
(bratio function for incomplete beta)

Maybe there is something in there that could help you patch the
discontinuities.
