Package: octave2.1
Version: 2.1.69-1
Severity: minor
There are several functions called "incomplete gamma function" in the
literature. I suggest this patch to relate this function to the
standard nomenclature - i.e. (using TeX) which one of
$ \gamma(a,z) $ with limiting value $ \gamma(a,\infty)=\Gamma(a) $
$ \Gamma(a,z) $ with limiting value $ \Gamma(a,\infty)=0 $
$ P(a,z) $ with limiting value $ P(a,\infty)=1 $
is being calculated.
