This repository contains materials used for a short, introductory tutorial on Cython (https://cython.readthedocs.io/en/latest/). A recording of the tutorial is available at https://youtu.be/KEmNYlpONiE
The directory contents are as follows:
cython_demo.py: A top-level calling function for the various implementations in this repository. The commands in this file are expected to be executed, one by one, in an IPython interactive session (https://ipython.org/) running in the root directory of this repository.invKepler_python.py: Reference Python implementation of Kepler time equation solution via Newton-Raphson iteration, used for benchmarking.invKepler_cython_v?.pyx: Three different versions of the baseline Python implementation, Cythonized to different degrees.setup.py: Setup file for building the 3 Cythonized versions.cver\invKepler_C.c: Fully C-translated version of the baseline Python implementation (with headerinvKepler_C.h).cver\invKepler_cython_v4.pyx: Cython wrapper for the full C version.cver\setup.py: Setup file for the C version of the code
In order to build the Cythonized extensions run:
python setup.py build_ext --inplace
You wil need to run this both at the root level as well as in the cver directory.
