pyflagser
=========
``pyflagser`` is a python API for the flagser C++ library by Daniel Lütgehetmann which computes the homology of directed flag complexes. Please check out the original `luetge/flagser <https://github.com/luetge/flagser>`_ GitHub repository for more information.
Project genesis
---------------
``pyflagser`` is the result of a collaborative effort between `L2F SA <https://www.l2f.ch/>`_, the `Laboratory for Topology and Neuroscience <https://www.epfl.ch/labs/hessbellwald-lab/>`_ at EPFL, and the `Institute of Reconfigurable & Embedded Digital Systems (REDS) <https://heig-vd.ch/en/research/reds>`_ of HEIG-VD.
Installation
------------
Dependencies
~~~~~~~~~~~~
``pyflagser`` requires:
- Python (>= 3.7)
- NumPy (>= 1.17.0)
- SciPy (>= 0.17.0)
User installation
~~~~~~~~~~~~~~~~~
If you already have a working installation of numpy and scipy, the easiest way to install pyflagser is using ``pip`` ::
python -m pip install -U pyflagser
Documentation
