Struct VietorisRipsComplex 

pub struct VietorisRipsComplex {
    pub simplices: Vec<Vec<usize>>,
    pub filtration_values: Vec<f64>,
    pub max_dimension: usize,
}

A Vietoris-Rips complex built from a point cloud. Simplices are added as epsilon grows — a k-simplex [v0,…,vk] appears at the maximum pairwise distance among its vertices.

Fields

simplices: Vec<Vec<usize>>

filtration_values: Vec<f64>

max_dimension: usize

Implementations

impl VietorisRipsComplex

pub fn build( cloud: &PointCloud, max_dimension: usize, max_eps: f64, ) -> Result<Self, PersistenceError>

Build the Vietoris-Rips complex up to max_dimension. For large point clouds you can pass max_eps to prune simplices whose filtration value exceeds it; pass f64::INFINITY to include everything.

pub fn n_simplices(&self) -> usize

pub fn simplex_dimension(&self, idx: usize) -> usize

Return the dimension of a simplex at given index.

pub fn simplices_of_dimension(&self, dim: usize) -> Vec<usize>

Indices of all simplices of a given dimension.

pub fn sorted_filtration(&self) -> Vec<(usize, usize)>

All (dimension, simplex-index) pairs sorted by filtration value then dimension.

Trait Implementations

impl Clone for VietorisRipsComplex

fn clone(&self) -> VietorisRipsComplex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VietorisRipsComplex

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

Formats the value using the given formatter.
