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 can create a graph structure using the GSP ToolBox, a gr

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;
  GFT_gui(G, f, paramplot)
