Struct SimplexTree 

pub struct SimplexTree {
    pub simplices: Vec<FilteredSimplex>,
}

Simplex tree data structure for filtration-based TDA.

Stores all simplices sorted by filtration value, supporting insertion, lookup, and filtration-order iteration.

Fields

simplices: Vec<FilteredSimplex>

All simplices, in arbitrary insertion order.

Implementations

impl SimplexTree

pub fn new() -> Self

Create an empty SimplexTree.

pub fn insert(&mut self, vertices: Vec<usize>, f: f64)

Insert a simplex defined by vertices at filtration value f.

Vertices are sorted before insertion.

pub fn from_vietoris_rips(vr: &VietorisRips) -> Self

Build a SimplexTree from a VietorisRips complex.

Inserts all vertices (at f=0), edges, and triangles at their respective filtration values (maximum edge length).

pub fn sorted_simplices(&self) -> Vec<&FilteredSimplex>

Return all simplices sorted by filtration value (ascending).

pub fn count_dim(&self, d: usize) -> usize

Number of simplices of dimension d.

pub fn max_filtration(&self) -> f64

Filtration threshold that includes all simplices (maximum filtration value).

Trait Implementations

impl Clone for SimplexTree

fn clone(&self) -> SimplexTree

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SimplexTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SimplexTree

fn default() -> SimplexTree

Returns the “default value” for a type.
