Fs = 0.5;
t = 0:1/Fs:10;
pulsewidth = 1e-6;
pulseperiods = 0:10;
x = pulstran(t,pulseperiods,@rectpuls,pulsewidth);
plot(t,x)
axis([0 10 0 1])
nwid = 1;
for nn = 2:nwid
x = pulstran(t,pulseperiods,@rectpuls,nn*pulsewidth);
subplot(nwid,1,nn)
plot(t,x)
axis([0 10 0 1])
D = dutycycle(x,Fs);
title(['Duty cycle is ' num2str(mean(D))])
end

You have these lines
nwid = 1;
for nn = 2:nwid
...
end
which effectively says for nn = 2:1, so nothing in the loop will run.

yes got it.
One more question.
I want to generate rectangular stripes as black white pattern. And width of the stripes should be half of the period of stripes.
Can you give any direction for this code?
