Struct PersistenceDiagram

pub struct PersistenceDiagram {
    pub intervals: Vec<PersistenceInterval>,
    pub n_points: usize,
}

Persistence diagram: collection of birth-death intervals.

Fields

intervals: Vec<PersistenceInterval>

All persistence intervals.

n_points: usize

Number of points in the input.

Implementations

impl PersistenceDiagram

pub fn betti(&self, dimension: usize, radius: f64) -> usize

Count features alive at a given radius (Betti number).

pub fn betti_curve(&self, dimension: usize, radii: &[f64]) -> Vec<usize>

Compute Betti curve: β(r) for a range of radii.

pub fn total_persistence(&self, dimension: usize) -> f64

Total persistence for a given dimension (sum of lifetimes, excluding infinite).

pub fn n_significant(&self, dimension: usize, min_persistence: f64) -> usize

Number of features with persistence above a threshold.
