calculate the peak to peak amplitude across 600 data points in 21 trials at two different points in the data in matlab

main.m
% first point of interest
first_idx = 100; % replace with your own index
% second point of interest
second_idx = 400; % replace with your own index

% calculate peak-to-peak amplitude across each trial
peak2peak = max(data(second_idx,:)) - min(data(first_idx,:));
