There is no 'MaxPeakHeight' so impose the maximum condition after the findpeaks call to limit the maximum peak values considered.
t = linspace(0, 10);
sig = sum(sin((1:2:9)'*2*pi*t));
[pks1,locs1] = findpeaks(sig);
figure
plot(t, sig)
hold on
plot(t(locs1), pks1, '^r')
hold off
grid
title('Plot All Peaks')
Lv = (pks1 <= 3); % Logical Vector To Keep Peaks <= 3
figure
plot(t, sig)
hold on
plot(t(locs1(Lv)), pks1(Lv), '^r')
hold off
grid
title('Plot Only Peaks <= 3')
There may be other ways to do this. I chose the ‘logical vector’ approach.
