Fields§

§total_persistence: f64

Sum of finite bar lengths.

§mean_persistence: f64

Mean finite bar length.

§median_persistence: f64

Median finite bar length.

§max_persistence: f64

Maximum finite bar length.

§n_finite: usize

Number of finite bars.

§n_essential: usize

Number of essential (infinite) classes.

§bottleneck_to_empty: f64

Bottleneck distance approximation to the empty diagram.

Equals the half-persistence of the most persistent finite bar.

Implementations§

Source§

impl BarcodeStatistics

Source

pub fn from_diagram(diagram: &PersistenceDiagram) -> Self

Compute statistics from a PersistenceDiagram.

Source

pub fn bottleneck_distance( a: &PersistenceDiagram, b: &PersistenceDiagram, ) -> f64

Approximate bottleneck distance between two diagrams.
