Struct Hierarchical 

pub struct Hierarchical { /* private fields */ }

A fitted dendrogram: the sequence of n−1 merges, each recorded as two representative original-point indices.

Implementations

impl Hierarchical

pub fn fit( x: &[f64], n: usize, p: usize, linkage: Linkage, ) -> Result<Self, LearningError>

Build the full dendrogram for a row-major n × p matrix under linkage.

pub fn labels(&self, k: usize) -> Vec<usize>

Cut the dendrogram into k clusters and return a label per original point (labels are 0..k, assigned in first-appearance order). k is clamped to 1..=n.

pub fn n_merges(&self) -> usize
