gplot

Purpose

Plot a graph theoretic graph.

Synopsis

gplot(A,xy)
gplot(A,xy,lc)

Description

gplot(A,xy) plots the graph specified by A and xy. A graph, G, is a set of nodes numbered from 1 to n, and a set of connections, or edges, between them. In order to plot G, two matrices are needed. The adjacency matrix, A, has A(i,j) nonzero if node i is connected to node j. The coordinates array, xy, is an n-by-2 matrix with the position for node i in the i-th row, xy(i,:) = [x(i) y(i)].

gplot(A,xy,lc) uses a specified line type and color instead of the default, solid red lines. See plot for a description of valid line types.

Examples

To draw the graph of half of a Bucky ball:

[B,xy] = bucky;
gplot(B(1:30,1:30),xy(1:30,:))
axis([-1.25  1.25  -1.25  1.25])
