fprintf end of line character

When I use fprintf to print multiple lines of text onto a txt file, it introduces a small rectangular box at the end of each line when ever I use '\n'. How would I print without getting that box at the end of each line of text in txt file?
Thanks, Ganesh

So, what is the problem? I thought it was due to the text editor that you are using. Why does '\r\n' solve the problem?

fid = fopen('test.txt','w');
fprintf(fid,'%.0f\t%.0f\r\n', [1:5; 6:10]);
fid = fclose(fid);

CHAR(10), which is the same as '\n', is a valid line break. Only the dull Windows Editor has problems with the interpretation, but this is a problem of a single outdated program. Some other editors, which can handle the line breaks correctly: The Matlab editor at least since Matlab 5.3, WordPad, Notepad++, Emacs, BBEdit, ...
Using the text mode to write files (fopen(FileName, 'wt')) has some side-effects, which may be very surprising for less experienced programmers.

What text editor are you using to view your text file? You need your text to appear in separated lines, right? Otherwise, you could just not to include the '\n'.
Try '\r' instead.

You should be opening your file with 'wt' instead of 'w' when you want to write text files.
