for a txt document of data create a script to extract the peak to peak amplitude of the h-reflex and m-wave in matlab

Here are the following steps to extract the peak to peak amplitude of the h-reflex and m-wave in Matlab:

  1. Convert the data into a string array using readlines function.
  2. Create arrays to store the h-reflex and m-wave amplitude data.
  3. Loop over each line of data string array.
  4. Extract the amplitude values for the h-reflex and m-wave from the data and append them onto the corresponding amplitude array.
  5. Calculate the peak to peak amplitude for the h-reflex and m-wave using the max and min functions.
  6. Print out the results.

Here is the code:

main.m
% read data from txt file
data = fileread('data.txt');
data = splitlines(data);

% initialize amplitude arrays
h_reflex_amp = [];
m_wave_amp = [];

% loop over each line of data
for i = 1:length(data)
    % extract the h-reflex and m-wave amplitudes from the data
    line = strsplit(data{i}, ',');
    h_reflex = str2double(line{1});
    m_wave = str2double(line{2});
    
    % append the amplitude values onto the corresponding array
    h_reflex_amp = [h_reflex_amp, h_reflex];
    m_wave_amp = [m_wave_amp, m_wave];
end

% calculate the peak-to-peak amplitudes
h_reflex_pp = max(h_reflex_amp) - min(h_reflex_amp);
m_wave_pp = max(m_wave_amp) - min(m_wave_amp);

% print out the results
fprintf('Peak-to-peak amplitude of h-reflex: %f\n', h_reflex_pp);
fprintf('Peak-to-peak amplitude of m-wave: %f\n', m_wave_pp);

Note: This assumes that the data in the txt file is in the format "H-Reflex Amplitude, M-Wave Amplitude" with each value separated by a comma.
