MATLAB: Clear figure content using clf

If you have open a new figure, it is cleared anyway. So there is no difference between

figure(); plot()

and

figure(); clf(); plot()

If you have you open a figure before a loop and then plot into this figure, the previous content is cleared by default, so you do not need a

figure(3), clf

The clf is useful when you have changed the default behaviour of clearing a figure before each plot using

hold on

MATLAB: How do i plot maximum values

You weren't actually calling the function. Secondly, the function had no input argument for threshold so I've included that. I also removed the loop as it simplifies the code and makes it more efficient.

ECG = load('ECG.csv');
f_s = 350; %Frequency of ECG [Hz]
Time = (0:length(ECG)-1)/f_s; %Number of samples divided by frquency
Amp = ECG(:,1); %ECG Amplitude
threshold = 100;
figure(), plot(Time,Amp,'b-') % I've pulled this out of the function
[Time_peak, Amp_peak] = findLocalMaxThreshold(Time,Amp,threshold)
hold on; plot(Time_peak, Amp_peak, '*r')
function [xp,yp] = findLocalMaxThreshold(x,y,threshold)
    idx = find(y(2:end-1) > (y(1:end-2)) & y(2:end-1) > y(3:end) & y(2:end-1) > threshold ) + 1;
    xp = x(idx);
    yp = y(idx);
end
