Nearest neighbor search algorithms including a ball tree and a vantage point tree.
The following example shows how to find two nearest neighbors in a ball tree.
use ndarray::{array, aview1};
use petal_neighbors::BallTree;
let points = array![[1., 1.], [1., 2.], [9., 9.]];
let tree = BallTree::euclidean(points).unwrap();
let (indices, distances) = tree.query(&aview1(&[3., 3.]), 2);
assert_eq!(indices, &[1, 0]); // points[1] is the nearest, points[0] the next.
