And now the script...


stint=0.001; # sampling time interval (seconds)
sfreq=1/stint; # sampling frequency (Hz)


t=[0:stint:1]'; # the sampling times column-vector

N=length(t); # number of sampling points

x=cos(2*pi*10*t)+cos(2*pi*25*t)+cos(2*pi*50*t)+ ... # the signal
column-vector
  cos(2*pi*100*t);
a=abs(fft(x)); # the Fourier transform

# plots

startx=20
starty=20
width=1200
height=800

fig=figure();
figure(fig, "position",[startx,starty,width,height]); ## window size

subplot(2,1,1)
plot(t,x)
ax=gca() ## axis object
set(ax, "fontsize", 12)
xlabel("Tempo (s)", "fontsize", 14)
ylabel("Amplitude", "fontsize", 14)
title("Sinal estacionário da pag. 6", "fontsize", 14);

subplot(2,1,2)
i=[1:N]';
xfreq=(i-1)*sfreq/N; # the frequencies column-vector
plot (xfreq(1:length(i)/2),a(1:length(i)/2));
ax=gca()
set(ax, "fontsize", 12)
xlabel("Frequência (Hz)", "fontsize", 14)
title("Transformada de Fourier do sinal estacionário da pag. 6",...
  "fontsize", 14)
