bottleneckDistance

function bottleneckDistance(a, b): number;

Defined in: metrics/topology.ts:312

Bottleneck distance between two general persistence diagrams of [birth, death] pairs. Use bottleneckH0 for degree-0 diagrams, which is far faster.

Parameters

Parameter	Type
a	Diagram
b	Diagram

Returns

number

Example

import { ripsH1, bottleneckDistance } from "@saehrimnir/sickle";

// Compares two H1 diagrams — arrays of [birth, death] pairs.
const circle = ripsH1(circlePoints);  // [[0.1256, 1.7526]] — one loop
const arc = ripsH1(arcPoints);        // [] — none

bottleneckDistance(circle, arc);  // 0.8135
