filtering data with a for loop and plot only filtered data

I want to filter my acceleration values and plot them afterwards.

ay.data contains all my accelerations and I just want to plot those that are greater than 1.5 and less than -1.5.

The background is to filter that it is a curve and not just a swinging.

Thanks a lot!

I tried that:

  quer = meas.ay.data;
  n = size(quer);
  i = zeros(n);
  
  for x = 1:length(i)
     if quer(x)> 4
        disp(quer(x));
        hold on;
        plot(quer(x));
        ii= quer(x);
     end  
  end

This can be done much more simply with logic indexing.

quer = meas.ay.data;
quer = quer(quer > 1.5 | quer < -1.5);
plot(quer)

Looking at your loop, I'm not entirely sure if this is what you're looking for, but that's mostly because I don't understand how the value of acceleration relates to the matrix position of > 4.
