Determining the distance between the peaks

Hello! I have a matrix, where for each column I have to determine the length of the peak. The problem is that the matrix is ​​large and you need to start with a specific row in this column. Help me the best way to do this.Peak = + 10 or -10 from the previous value

for Vatl(i)+en>en; 
% en is how much to add to each value
% Vatl is the value to start counting
     MaxPeak1=VatlPoint(Vatl(i)-en:Vatl(i));
     MaxPeak2=VatlPoint(Vatl(i):end);
      [pks1,locs1] = findpeaks(MaxPeak1,-10:10,'MinPeakDistance');
      [pks2,locs2] = findpeaks(MaxPeak2,-10:10,'MinPeakDistance');
end

Why is this option not working

In the documentation you can find the correct syntax. You need to provide the Name argument first and then the Value argument:

[pks1,locs1] = findpeaks(MaxPeak1,'MinPeakDistance',10);

Note that the 10 here is in units of samples.
