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.
Remarks
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.
Examples
To draw half of a Bucky ball with asterisks at each node,
k = 1:30;
[B,XY] = bucky;
gplot(B(k,k),XY(k,:),'-*')
