Dear all,
I'm Michele Ginesi, the student working on special functions for GSoC2017.
During the last period I saw on this mailing list some discussions about
the reorganization of special functions in Octave. I saw there is the
idea to use the standard math library of C++ or GSL library.
Unfortunately, as I explained in the last post on my blog [1], I think
it is not the case to fully substitute the old (but still the more
accurate) Fortran code present in the Amos library.
For example, for what concern Bessel functions, I would suggest to
"unlock" the Amos, since the bug related to them [2] is caused by the
fact that if the magnitude of the input is too large, the output is
simply not computed (you can find more details on [1], as well as other
thoughts relative to incomplete gamma and beta functions).
I hope you can give me some opinions and/or suggestions.
Thank you for your kind attention.
