To plot the model error against time
显示 更早的评论
Anyone please help me plot the model error against time in the subplot(212)
V=20;
t_sim=30;
sample_distance=0.2;
ts=sample_distance/V;
collect_ts=ts*1;
t_plot=(0:collect_ts:t_sim);

Priya, the "correct" syntax for subplots is:
subplot(2,1,1) % notice the commas
Other than that, what is
size(deltaSignal)
size(percentageDifference)
And finally, I believe what you are trying to do is:
plot(deltaSignal,percentageDifference)

With
t_sim = 30;
you could simply do
t_psim = linspace(0,t_sim,length(percentageDifference))
plot(t_psim,percentageDifference)
You are using as x-axis deltaSignal(:) which does not seem to be related to time. Am I missing something?

I do not know what exactly your variables mean, I am trying to interpret based on your code and information. It seems that in
deltaSignal = abs(simout_ss(:,19)-simout_b(:,19));
you compute the difference between two signals (models?) and in
percentageDifference=deltaSignal./simout_b(:,19);
you calculate the relative difference ( not percentage; for that you need to multiply the result by 100). So using
plot(t_psim,percentageDifference)
should plot what you are looking for.
