Thomas Neidhart commented on MATH-1066:
---------------------------------------
Sorry for the late feedback, you surely put a lot of effort into this patch.
We had some bad experience with code translated too literally from fortran as
it tends to be very difficult to understand / maintain.
Having said that and quickly looking at your patch, I would say that this
functionality is definitely interesting for CM but would still need a lot of
work to make it ready for committing.
The main problem I see with the rjbesl method, and I do not know if this could
be re-written in a more Java-friendly way without breaking functionality.

> According to the Wish List, special functions are a priority item to be added
> to ACM. As Bessel functions (http://en.wikipedia.org/wiki/Bessel_function)
> are listed by name, I have translated some Fortran code from Netlib --
> specifically, http://www.netlib.org/specfun/rjbesl -- for Bessel functions of
> the first kind.
