There is no way that you could get a succession of A's using, This does however correctly print the character value of 'A' and. What's in text? This creates newlines. automatically add a newline at the end: the file will just suddenly end. If the writing that produces the furthest writing into the file does not end with \n then MATLAB will. And again, the output of the fprintf looks perfectly fine, except for the fact that no new lines are created. However this is a mistaken notion: no final \n is automatically added, and any appending to the file will pick up right where the file left off, adding to the end of that line. Only the Windows Editor fails to interprete this. I have checked the file in the matlab editor, notepad, and several different other text editors, and all show the same.
