Examples

The following example shows how to cluster points using DBSCAN.

use ndarray::array;
use petal_clustering::{Dbscan, Fit};

let points = array![[1., 2.], [2., 2.], [2., 2.3], [8., 7.], [8., 8.], [25., 80.]];
let clustering = Dbscan::new(3.0, 2).fit(&points);

assert_eq!(clustering.0.len(), 2);        // two clusters found
assert_eq!(clustering.0[&0], [0, 1, 2]);  // the first three points in Cluster 0
assert_eq!(clustering.0[&1], [3, 4]);     // [8., 7.] and [8., 8.] in Cluster 1
assert_eq!(clustering.1, [5]);            // [25., 80.] doesn't belong to any cluster
