Hello

I'm sure this is a simple fix, but how can I measure the average of a signal at specified x points?

E.g. I want to measure the mean at 0 - 0.2 in the below exampe, and then again at 0.5-0.7

What code should I use please?

Thanks

在 MATLAB Online 中打开

Try this:

t = ...;                                            % Time Vector
s = ...;                                            % Signal Vector
t1 = t <= 0.2;
t2 = (t >= 0.5) & (t <= 0.7);
s1 = mean(s(t1));
s2 = mean(s(t2));
