%description
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>.
