    t=0:0.001:2;                   
    x=chirp(t,0,1,150);

Now to find the short-time Fourier transforms

    % without a window
    win = ones(200,1);
    [S,F,T] = spectrogram(x,win,100,200,1000);

    % with a hamming window
    win = hamming(200);
    [Swin,Fwin,Twin] = spectrogram(x,win,100,200,1000);
