GSP_PLOT_SGRAM - Plot graph spectrogram

Usage

gsp_plot_sgram( G,A );
gsp_plot_sgram( G,A,param );

Input parameters

`G`	Graph
`A`	Graph windowed Fourrier transform
`param`	Structure of optional parameter

Output parameters

non none

Description

param is a structure of optional parameter with

param.colorbar: Use the colorbar (default 1)

Example:

N = 15;
G = gsp_ring(2*N);
G = gsp_compute_fourier_basis(G);
x = [0:N,(N-1):-1:1]';
s = 3;
g = exp(-(x-1).^2/s^2);
f = gsp_localize(G,g,N);
c = gsp_gwft(G,f,g);
gsp_plot_sgram(G,c);
