Can someone please help me with the code for finding the signal peaks in the below figure .
I hae tried using for loops, and also MATLAB function findpeaks() . I am new to MATLAB and I am not sure if I am doing this correctly. Please help me.

And how can we do it by code? You should explain why some peaks are ignored, If there is no explanation it's impossible to do it by program.

[peaks,index]=findpeaks(y)
for k=1:numel(peaks)
ii=index(k);
jj=0;
if abs(y(ii)/y(ii-1))>=3 & abs(y(ii)/y(ii+1))>=3
jj=jj+1
real_peak(jj)=peaks(k)
index_peak(jj)=ii
end
end
