General Information

This website provides information about the software Graph Fourier Transform Interactive GUI which is developed in Matlab

Download

Click here to download the GFT-IGUI

Installation

  • The code is written in Matlab(c) version R2014b.
  • To install the code, simply unpack the directory in a Matlab folder.

Getting Started

  • Before running GFT-IGUI you need to be sure you have installed the GSP ToolBox.
  • After that you need to do the following:
    • create a graph structure using the GSP ToolBox
    • create a plot parameters structure
    • create a signal to be analyzed, and
    • call the GUI

1 Sensor network example

  % Creating a graph structure using the GSP ToolBox
  G = gsp_sensor(10, param);
  
  % Defining plot parameters
  paramplot.show_edges = 1;
  paramplot.bar = 1;
  paramplot.vertex_size = 3;
  paramplot.cp = [0 0 0];
  
  % Defining a signal of the graph G to be analyzed by the GFT
  N = 10;
  f = rand(N,1)*20 + 60 + sin([1:N]'/5)*20;
  
  % Call the GUI
  GFT_gui(G, f, paramplot)

2 Community graph example

  % Creating the Graph
  N = 12;
  param.Nc = 3;
  G = gsp_community(N);
  
  % Creating plot parameters
  paramplot.show_edges = 1;
  
  % Creating the signal
  f = rand(N,1);
  
  % Call the GUI
  GFT_gui(G, f, paramplot);
