calculate the peak to peak amplitude of the m-wave and h-reflex for an emg signal of 21 trials in matlab

main.m
% Assume your data is stored in 'emg_data', a 21-by-n matrix
m_wave_ppa = zeros(1, 21); % pre-allocate a vector to store the M-wave PPA for each trial
h_reflex_ppa = zeros(1, 21); % pre-allocate a vector to store the H-reflex PPA for each trial

for i = 1 : 21 % loop through each trial
    trial_data = emg_data(i, :); % extract the EMG signal for the current trial
    m_wave_ppa(i) = max(trial_data) - min(trial_data); % calculate the M-wave PPA
    h_reflex_ppa(i) = max(trial_data(50 : 100)) - min(trial_data(50 : 100)); % calculate the H-reflex PPA (assuming the H-reflex is between 50 and 100 samples)
