Tutorials

The main features of PolyKin are explained and illustrated through a series of tutorials based on Jupyter notebooks, which can be launched online via Binder.

Installation

PolyKin currently runs on Python>=3.10. You can install it from PyPI via pip (or poetry):

pip install polykin
# poetry add polykin

Alternatively, you may install it directly from the source code repository:

pip install git+https://github.com/HugoMVale/polykin.git
# poetry add git+https://github.com/HugoMVale/polykin.git
