why the findpeaks function cant find several peaks in my signal ?? as i observed, it only happen when the peak is flat, as i marked the noticed peaks with red circles from the findpeaks function, and it couldnt notice any flat peaks. Screenshot (84).png

i have been struggling like a few days to find the answer in the internet and i got nothing. Please help. I really appreciate any kind of answer. Thank you in advance.

If you have R2017b or later, use the islocalmax function, specifcially as described in the Flat Maxima Regions documentation section, using the FlatSelection name-value pair.
