The first sample is excluded despite being the maximum in findpeaks(). How to exclude the last peak?

Assuming you mean the peak that comes with the final sample can't you just delete the last peak from the list of peaks that get found? It may need a test to check the peak location is equal to the last index as it may be a trough instead in some cases, but that depends on your data.

The findpeaks function has a number of name-value pair arguments you can use. For example, if you only want one peak (the first one that meets other criteria you may set), set 'NPeaks',1 in the argument list. Others you can set that might do what you want are 'MinPeakDistance' and 'Threshold'.

I would probably use these two arguments: 'MinPeakDistance',100,'NPeaks',1. You will have to experiment to get the result you want. Without your data, it is not possible to provide exact code.
