How do you find the mean values of specified peak values using "findpeaks" function and displaying it.
Below is my code of generating this graph
load a1.mat
data = a1(:,2)
findpeaks(data,"MinPeakHeight",50,"MinPeakDistance",290)

% load a1.mat
% data = a1(:,2)
% sample data
x = linspace(0,1,1000);
Pos = [1 2 3 5 7 8]/10;
Hgt = [3 4 4 2 2 3];
Wdt = [2 6 3 3 4 6]/100;
for n = 1:length(Pos)
Gauss(n,:) = Hgt(n)*exp(-((x - Pos(n))/Wdt(n)).^2);
end
data = sum(Gauss);
[pks, loc] = findpeaks(data,"MinPeakHeight",2.50,"MinPeakDistance",10, "Annotate", "peaks");
plot(x, data, "b-", x(loc), pks, 'rv')
mp = mean(pks);
