I wish to find the mean of all peaks from the positive axis in Figure 1.
I tried
pks = findpeaks(y);
but it includes some negatif value.
How to filter out the nagative peaks and remain the positive peaks?

thresh=0; % or whatever level you wish
pks = findpeaks(y,'MinPeakHeight',thresh);
Read the doc carefully; findpeaks has all kinds of options you'll probably find useful.

NB I defined the variable threshold after first just typing in the '0' value...fixed up the Answer to reflect using the variable...dpb

Hi,
Here is a simple and fast answer to peak only positive peaks of your data:
Y = DATA; % This is your data
X = findpeaks(Y);
X_pos = X(X>0); % Selects only positive peaks
Good luck
