Follow-up Comment #44, bug #47800 (project octave):
Dear all,
I have made some minor modifications to gammainc.m and __gammainc_lentz.cc
(files #39669 and #39670 )in such a way to adapt to the class of the input (as
the actual gammainc do: if one between x and a is single, then the output is
single as well).
Then I tried to make a patch (file #39668 ). I was able to build octave with
this, but it's the first time I try to make a patch in which there is more to
do than to modify a single file, so I'm not sure it is "well-made". So if
everyone has some suggestion, I would like to help in making this patch
definitive.
