Plot in real time
显示 更早的评论
i have a code that i wrote to perform an output of simple harmonic function. and when i plot the result in realtime (as is it going through the for loop) rather than plotting y versus time, it is plotting two point (1,time) and (2,y) and draws a line in between.
any help is appreciated as i am new at using matlab
clf;
A=3.3;
W=6.28;
time=0;
p=0;
for t = (0:0.01:2)
y=A*sin(W*t);
time = time +0.01;
p=[time,y];
graph=plot(p);
drawnow;
p
pause(0.1)
end

Dear Jerry try this:
A = 3.3;
W = 6.28;
for t = 0:0.01:2
y = A * sin(W * t);
plot(t, y, 'g*'), hold on
drawnow;
pause(0.1)
end
I hope it helps. Good luck!
