phutil: Persistence Homology Utilities
A low-level package for hosting persistence data. It is part of the
'TDAverse' suite of packages, which is designed to provide a collection of
packages for enabling machine learning and data science tasks using
persistent homology. Implements a class for hosting persistence data, a
number of coercers from and to already existing and used data structures
from other packages and functions to compute distances between persistence
diagrams. A formal definition and study of bottleneck and Wasserstein
distances can be found in Bubenik, Scott and Stanley (2023)
<doi:10.1007/s41468-022-00103-8>. Their implementation in 'phutil' relies on
the 'C++' Hera library developed by Kerber, Morozov and Nigmetov (2017)
<doi:10.1145/3064175>.
