Thank you very much for the help offered.
I installed the statistics package like this:
apt-get install octave-statistics
but when trying this in octave:
c =combnk(1:4,2)
I seems like octave doesn't find the extra functionality from the
statistics package:
error: `combnk' undefined near line 1 column 4

octave:2> help combnk
error: help: `combnk' not found

I'd first wish to get this working before looking into your other suggestions

kind regards,
jean
