New submission from Pablo Galindo Salgado <pablog...@gmail.com>:
After repeatedly having to add 3rd party libraries only for the these functions or having to implement them myself quick and dirty based on numerical integration, I suggest add the Bessel functions of the first and second kind to the math module. These functions tend to appear a lot (but not restricted to) when evaluating systems that are defined on cylindrical geometries, restrictions or approximations (like the proximate solution to Kepler's equation as a truncated Fourier sine series) and many other special functions can be described as series involving them. Based on the fact that many libc implementations include them I think the cost-benefit of exposing them when available is acceptable. ---------- components: Extension Modules messages: 350477 nosy: mark.dickinson, pablogsal, rhettinger priority: normal severity: normal status: open title: Add the Bessel functions of the first and second kind to the math module type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37946> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
