How to plot shifting square pulse
显示 更早的评论
I cant figure out how to plot a graph of a square pulse shifting to the right across the x axis. This is currently what I have, but it just outputs a singular square wave, and I want a moving plot that shifts to the right with a step of 0.5. Any help is appreciated, thank you!
x = linspace(-5,5,10000);
pulse = rect(x,2);
%plot(x,pulse);
tau = 0;
for k = 1:length(x)
pause(3)
plot(x - tau,pulse);
drawnow;
tau = tau + 0.5;
end
function a = rect(t,len)
x = zeros(length(t));
for i=1:length(t)
if abs(t(i)) > len/2.0
x(i) = 0;
else
x(i) = 1;
end
end
a = x;
end

It is difficult to understand your code.
Here is a slightly simpler version:
x = linspace(-5, 5, 1000);
pulse = [0 ones(1,20) 0];
figure
for k = 1:numel(x)-numel(pulse)
plot(x(k:k+numel(pulse)-1), pulse)
axis([min(x) max(x) 0 1.5])
drawnow
end
Adapt it to do what you want.
Have fun with it!
