Function File: gplot3 (a, xyz)

Function File: gplot3 (a, xyz, line_style)

Function File: [x, y, z] = gplot3 (a, xyz)

Plot a 3-dimensional graph defined by A and xyz in the graph theory sense. A is the adjacency matrix of the array to be plotted and xy is an n-by-3 matrix containing the coordinates of the nodes of the graph.

The optional parameter line_style defines the output style for the plot. Called with no output arguments the graph is plotted directly. Otherwise, return the coordinates of the plot in x and y.

Demonstration 1

The following code

 ## Define adjacency matrix of a graph with 5 nodes
 A = [0, 1, 0, 0, 1;
      1, 0, 1, 1, 1;
      0, 1, 0, 1, 1;
      0, 1, 1, 0, 1;
      1, 1, 1, 1, 0 ];
 
 ## Define 3D points of the nodes
 xyz = [2,   1, 3/2;
        3,   2, 2;
        8/3, 3, 1;
        5/3, 3, 1;
        1,   2, 2 ];

 ## Plot the 3D graph
 gplot3 (A, xyz);

Produces the following figure
