Get Maxima from changing areas with max command

i have to get peak values from temperature measurements. Therefore it is important to take one double matrix for getting the start and end points of areas I want to calculate the maxima from. Another double matrix includes the measured values I finally want to get the peaks out of. E.g The first matrix is going [1 77 244 531 till 14400] and the other one has double values in a 14400x1 matrix. Now I want to get the peaks from the 14400x1 matrix in the areas from 1 to 77, 77 to 244, 244 to 531 etc. In the end I should get a vector with all peaks inside of it... I hope someone can understand my problem... Thanks in advance for your help! I thought it should be done similar to this:

% 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

index=1;
for k1=  PV_change(1:end-1)'; 
    k2=  PV_change(2:end)';

    PEAKS(index)=max(TempR1(k1:k2));
    index=index+1;
end
