MATLAB: I need to use ‘for loop’ to read the names from a text file using ‘fgetl’ function. How to do that

Question

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!!

Answer 1

fid = fopen('filename.txt');
line1 = fgetl(fid);
res=line1;
while ischar(line1)
    if ischar(line)
        res =char(res,line1)
    end
   line1 = fgetl(fid);
end
fclose(fid);
