how to read the total number of lines in a text file in matlab in matlab

You can read the total number of lines in a text file in MATLAB by using the textscan function in combination with fopen and feof. Here is an example code snippet to achieve this:


main.m
fileID = fopen('yourfile.txt', 'r');
numLines = 0;

while ~feof(fileID)
    textLine = fgetl(fileID);
    if ischar(textLine)
        numLines = numLines + 1;
    end
end

fclose(fileID);

disp(['Total number of lines in the file: ', num2str(numLines)]);
255 chars
14 lines

Make sure to replace 'yourfile.txt' with the actual path to your text file.
