In MATLAB, you can use the "textscan" function to read the data from the text file and extract the desired values. Below code snippet can help you in achieving the desired result, you can take idea from it and can implement it according to your needs
fid = fopen('your_file.txt', 'r');
% Read the lines from the file
lines = textscan(fid, '%s', 'Delimiter', '\n');
lines = lines{1};
% Close the file
fclose(fid);
% Extract the desired values
sample1_line3 = strsplit(lines{4}, ',');
sample1_line3 = sample1_line3(3:5);
sample1_line4 = strsplit(lines{5}, ',');
sample1_line4 = sample1_line4(3:4);
sample1_line5 = strsplit(lines{6}, ',');
sample1_line5 = sample1_line5(3:4);
sample2_line1 = strsplit(lines{9}, ',');
sample2_line1 = sample2_line1(3:4);
