Teia
A persistent homology library and its command line interface.
This crate provides
- Simplicial complex
- Column reduction algorithm
- Persistence pairing algorithm
Command line interface
The CLI program has two subcommands: homology and persistence.
How to build
First, if you not have Rust environment, you get it from https://rustup.rs/ and install it.
Then you clone this repository with git clone https://github.com/ShotaroTsuji/teia and build it with cargo build --release.
Subcommands
homology: computes the generators of the homology groups of the given complex.persistence: computes the persistent homology groups of the given complex.
Input file format
- Simplicial complex (text file) : A simplex is represented as numbers separated with whitespace. Each simplex is written in each line.
There is the example files examples/torus.txt and examples/cube.txt.
Future work
- Construction of the filtration from given filtration values.
- Persistent cohomology algorithm.
- Lower-star complex.
- Vietoris-Rips complex.
