boys

A Rust library for calculation of the Boys function

via a number of methods:

• An "exact" algorithm originally from Radovan Bast.
• A non-clean-room reimplementation of Michael Böhme's algorithm.

System dependencies

The GNU Scientific Library (GSL) is used via the rgsl crate to provide the gamma and incomplete gamma functions for the exact implementation and the error function for Michael Böhme's algorithm.

OS/distro	install command
Debian/Ubuntu	sudo apt-get install libgsl0-dev
Arch Linux	sudo pacman -S gsl
