Function transitivity_avglocal_undirected 

pub fn transitivity_avglocal_undirected(
    graph: &Graph,
    mode: TransitivityMode,
) -> IgraphResult<f64>

Average local transitivity (clustering coefficient).

Computes the local transitivity for each vertex and returns the mean.

• mode: how to handle vertices with degree < 2.
  • TransitivityMode::Nan: exclude them (result is NaN if no vertex qualifies).
  • TransitivityMode::Zero: include them with transitivity 0.

Examples

use rust_igraph::{Graph, transitivity_avglocal_undirected, TransitivityMode};

// Triangle: all vertices have local transitivity 1.0
let mut g = Graph::with_vertices(3);
g.add_edge(0, 1).unwrap();
g.add_edge(1, 2).unwrap();
g.add_edge(0, 2).unwrap();
let avg = transitivity_avglocal_undirected(&g, TransitivityMode::Nan).unwrap();
assert!((avg - 1.0).abs() < 1e-10);
