compute harmonic centrality
(optional) a vertex of G
HarmonicCentrality returns the harmonic centrality for a specified vertex in the given graph G, or if no vertex is specified, returns a list of the harmonic centralities for each vertex in G.
The harmonic centrality of a vertex v is the sum of the reciprocal of the graph distance from u to v for every other vertex u in G.
Compute the harmonic centrality for a specified graph.
G≔Graph 1: an undirected unweighted graph with 6 vertices and 8 edge(s)
The GraphTheory[HarmonicCentrality] command was introduced in Maple 2020.
