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 3.9+. 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:

git clone https://github.com/HugoMVale/polykin.git
cd polykin
pip install . 
# poetry install
