faces

Generate all unique faces of a given dimension from simplices

Provides an implementation of simplicial complexes for
Topological Data Analysis (TDA). The package includes functions to
compute faces, boundary operators, Betti numbers, Euler characteristic,
and to construct simplicial complexes. It also implements persistent
homology, from building filtrations to computing persistence diagrams,
with the aim of helping readers understand the core concepts of
computational topology.
Methods are based on standard references in persistent homology such as
Zomorodian and Carlsson (2005) <doi:10.1007/s00454-004-1146-y> and
Chazal and Michel (2021) <doi:10.3389/frai.2021.667963>.
