I am trying to use the findpeaks function in my code but in a specific range.In the code below you can see I have a plot of x2 and y2.From this plot, I want to find the peak at x2 values between 90 and 120.BUt my code doesnt work for the peaks and shows a blank graph.Any help would be appreciated.
Data = xlsread('test.xlsx');
%% Step 2 data
x2 =Data(655:8466,6); % Sample temprature
y2 =Data(655:8466,3); % Umsubstracted temprature
title('Step 2 Data')
[pks, locs]= findpeaks((x2(90:120)),'Npeaks',1)
title('Peak for step 2')
