write a matlab code that will extract the peak-to-peak amplitude of the m-wave and h-reflex at each stimulation step an create a graph of raw units in matlab

Here's an example MATLAB code to extract the peak-to-peak amplitude of the m-wave and h-reflex at each stimulation step and create a graph of raw units in MATLAB:

main.m
% Load data
load('data.mat'); % replace with your data filename

% Define constants
fs = 1000; % sampling frequency in Hz
prestim_time = 50; % prestimulus time in ms
poststim_time = 200; % poststimulus time in ms
stim_duration = 1; % stimulus duration in ms
num_stim = length(data); % number of stimulation steps

% Preallocate output variables
mwave_pp = zeros(1,num_stim);
h_reflex_pp = zeros(1,num_stim);

% Loop through each stimulation step
for i = 1:num_stim
    % Get the stimulus onset time
    stim_onset = (i-1)*stim_duration + prestim_time;
    
    % Get the window for prestimulus baseline
    prestim_window = round((stim_onset - prestim_time/2):(stim_onset - prestim_time/4));
    
    % Get the window for m-wave and h-reflex peak-to-peak amplitude
    resp_window = round((stim_onset + stim_duration):(stim_onset + poststim_time));
    
    % Get the data for the windows
    prestim_data = data(prestim_window);
    resp_data = data(resp_window);
    
    % Get the peak-to-peak amplitudes
    mwave_pp(i) = peak2peak(resp_data);
    h_reflex_pp(i) = max(resp_data) - min(prestim_data);
end

% Create a plot of peak-to-peak amplitudes
figure;
plot(1:num_stim, mwave_pp, 'b', 1:num_stim, h_reflex_pp, 'r');
xlabel('Stimulation step');
ylabel('Peak-to-peak amplitude (raw units)');
legend('M-wave', 'H-reflex');
title('M-wave and H-reflex peak-to-peak amplitudes at each stimulation step');

This code assumes that your data is stored in a variable named data and that each element of data corresponds to a single time point. You can replace the filename and variable names as necessary.

The code first defines the constants, including the sampling frequency, stimulus timing parameters, and number of stimulation steps. It then preallocates the output variables mwave_pp and h_reflex_pp as arrays of zeros.

The code then loops through each stimulation step and extracts the prestimulus and response data for each window. It then calculates the peak-to-peak amplitude of the response for both the m-wave and h-reflex.

Finally, the code creates a plot of the peak-to-peak amplitudes for each stimulation step using the plot function. The x-axis shows the stimulation step number, while the y-axis shows the peak-to-peak amplitude in raw units. The code also adds axis labels, a legend, and a title to the plot.
