% PV_change is a 84x1 double going from [1;77;244;531;...;13608] it should give the starting and endpoints for the maxima areas.
% TempR1 is a 14400x1 double with all measured values, now I want to get all maxima from the specified areas in the former specified matrix...
% So I should get 1 maximum from area 1 to 77, 1 maximum from 77 to 244 and so on... Best would be if these maximas could be stored in a vector PEAKS
% Get peak start and ends into their own separate arrays.
peakStarts = PV_change(1 : end - 1); 
peakEnds = PV_change(2 : end - 1); 
% Now find the max value of all the peaks.
for k = 1 : length(peakStarts)
    % Get starting and stopping indexes for this peak.
    k1 = peakStarts(k);
    k2 = peakEnds(k);
    % Get the max value of TempR1 between those indexes, inclusive.
    peakAreas(k) = max(TempR1(k1 : k2));
end
