This is my MATLAB code:
[H, f]=make_fft(data(:,2),data(:,1)); %my function
How can I see values of the plot in a vector? I should find the first and second maximum along the y axis

You mean this?
H_sorted=sort(H); %sort vector "H" in ascending order
idx=find(H==H_sorted(end-1)); %find the index of the second maximum value in vector "H"
2nd_max_value=H(idx); %this is the second maximum value of vector "H"
