[SciPy-User] Special Function Question

[Mickael]

Hi Sean,

>> Is there a reason that gammainc in scipy.special is the normalized version?

this function is not really normelized, since the gamma function is
completely defined

==> on |R_(+)^(*) see (Bohr–Mollerup theorem)
==> and for complexe where, Re(z)>0

so all values must be positives... ???
