write matlab code that will extract the peak-to-peak amplitude of the m-wave and h-reflex waveforms at each stimulation step with pre-processing seps in matlab

main.m
% Pre-processing steps
% Assuming your raw data is in variables called mwave_data and hwave_data
% Apply any filtering or artifact removal techniques as necessary
% Define the stimulation step duration in seconds
stim_duration = 1.0;

% Extract the peak-to-peak amplitude for each stimulation step
% Assuming each stimulation step is separated by a period of no stimulation
% Define the duration of the inter-stimulus interval in seconds
isi_duration = 0.5; 

% Calculate the number of samples in the stimulation step and isi
stim_samples = stim_duration * sample_rate; % sample_rate is the sampling frequency of your data
isi_samples = isi_duration * sample_rate;

% Calculate the total number of stimulus steps
num_steps = floor(length(mwave_data) / (stim_samples + isi_samples));

% Initialize arrays to store the results
mwave_ppa = zeros(num_steps, 1);
hwave_ppa = zeros(num_steps, 1);

for i = 1:num_steps
    % Calculate the indices for the current stimulation step
    start_idx = (i-1)*(stim_samples + isi_samples) + 1;
    end_idx = start_idx + stim_samples - 1;
    
    % Extract the M-wave and H-reflex waveform for the current stimulation step
    mwave_step = mwave_data(start_idx:end_idx);
    hwave_step = hwave_data(start_idx:end_idx);
    
    % Calculate the peak-to-peak amplitude for each waveform
    mwave_ppa(i) = max(mwave_step) - min(mwave_step);
    hwave_ppa(i) = max(hwave_step) - min(hwave_step);
