# VertexList

VertexList[g]

gives the list of vertices for the graph g.

VertexList[g,patt]

gives a list of vertices that match the pattern patt.

VertexList[{vw,},]

uses rules vw to specify the graph g.

# Details

• VertexList is also known as nodes or actors.
• VertexList returns the list of vertices in the order used by the graph g.

# Examples

## Basic Examples(3)

The vertex list for an explicitly constructed graph:

The vertex list for a parametrically constructed graph:

Find all vertices that match a pattern:

## Scope(5)

VertexList works with undirected graphs:

Directed graphs:

Use rules to specify the graph:

Use patterns to select a subset of vertices:

VertexList works with large graphs:

## Applications(2)

Find all vertices with a given annotation:

Highlight the vertex by the vertex degree:

## Properties & Relations(7)

VertexCount can be found using VertexList:

VertexIndex gives the position of a vertex in VertexList:

Use VertexQ to test if a vertex is a member of VertexList:

Vertices are taken in the order they appear in the list of edges:

The order can be modified with an explicit vertex list:

Rows and columns of the adjacency matrix follow the order given by VertexList:

Rows of the incidence matrix correspond to VertexList:

Vertices can be specified in Graph:
