GraphTheory[Digraph]

Calling Sequence

Digraph(V)

Digraph(L)

Digraph(V, L)

Digraph(V, E, A, W)

Parameters

V

-

list of vertices or number of vertices

E

-

set of arcs

L

-

Array or list of sets of vertices indicating vertex neighbors

A

-

adjacency Matrix (edge weights)

W

-

(optional) one of weighted or unweighted, or an equation weighted=true or false

Description

• 

The Digraph command creates a digraph (directed graph) with the given parameters. The input parameters may appear in any order; however, they must be compatible.

• 

A detailed description of the meaning of each parameter is found in the Graph help page.
