When you first create the file,
fid = fopen('Yourfile.txt', 'wt');
Each time you want to add something to it after having already closed it,
fid = fopen('Yourfile.txt', 'at');

Yes, you use \n in files. But when you write something to a file and then close it, there is no \n automatically added: opening for append and writing something else would continue the exact same line.
