GSP_SENSOR - Create a random sensor graph

Usage

G = gsp_sensor(N);
G = gsp_sensor( );
G = gsp_sensor(N, param);

Input parameters

- N

Number of nodes (default 128)

- param

Structure of optional parameters

Output parameters

- G

Graph

Description

This function creates a 2 dimensional random sensor graph. All the coordinates are between 0 and 1.

param is an optional structure with the following field

• param.verbose: display parameter - 0 no log - 1 display the errors (default 1)
• param.N_try: Number of attempts to create the graph (default 10)
• param.distribute: To distribute the points more evenly (default 0)
• param.connected: To force the graph to be connected (default 1)
• param.nnparam: optional parameter for the gsp_nn_graph

Example:

G = gsp_sensor(300);
paramplot.show_edges = 1;
gsp_plot_graph(G,paramplot);
