gplot

Plot nodes and links representing adjacency matrix

Syntax

gplot(A,Coordinates)
gplot(A,Coordinates,LineSpec)

Description

The gplot function graphs a set of coordinates using an adjacency matrix.

gplot(A,Coordinates) plots a graph of the nodes defined in Coordinates according to the n-by-n adjacency matrix A, where n is the number of nodes. Coordinates is an n-by-2 matrix, where n is the number of nodes and each coordinate pair represents one node.

gplot(A,Coordinates,LineSpec) plots the nodes using the line type, marker symbol, and color specified by LineSpec.

Plot Graph of Nodes Using Asterisks

Plot half of a "Bucky ball" carbon molecule, placing asterisks at each node.

k = 1:30;
[B,XY] = bucky;
gplot(B(k,k),XY(k,:),'-*')
axis square

Tips

For two-dimensional data, Coordinates(i,:) = [x(i) y(i)] denotes node i, and Coordinates(j,:) = [x(j)y(j)] denotes node j. If node i and node j are connected, A(i,j) or A(j,i) is nonzero; otherwise, A(i,j) and A(j,i) are zero.
