There is a list of 80 test subject names in a text file, and I have to use the for loop function to read the names of the first 40 subjects using fgetl function. How do I write the code in MATLAB.

Thanks!!

Reading the help is always a good idea. In there is this example:

Examples
Read and display the file fgetl.m one line at a time:
fid = fopen('fgetl.m');
tline = fgetl(fid);
while ischar(tline)
    disp(tline)
    tline = fgetl(fid);
end
fclose(fid);
