characteristic polynomial of an undirected graph

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

charpoly(G, x)

Parameters

G

-

undirected graph or network

x

-

variable in characteristic poly

Description

• 

Important: The networks package has been deprecated.  Use the superseding command GraphTheory[CharacteristicPolynomial] instead.

• 

This routine computes the characteristic polynomial of the adjacency matrix of G expressed as a polynomial in x.

• 

As part of the networks package it is normally loaded via with(networks) but the full name of networks['charpoly'](...) can also be used.
