elpigraph-python 0.1.0

No project description provided

Description

This package provides a Python implementation of the ElPiGraph algorithm with cpu and gpu support. A self-contained description of the algorithm is available here or in the paper

It replicates the R implementation, coded by Luca Albergante and should return exactly the same results. Please open an issue if you do notice different output. Differences between the two versions are detailed in differences.md. This package extends initial work by Louis Faure and Alexis Martin.

A native MATLAB implementation of the algorithm (coded by Andrei Zinovyev and Evgeny Mirkes) is also available
