Printing to text file

Pretty simple. I want to print this to a text file:

4
1
2
3
4

but instead I am getting this:

41234

Here's my code:

z = 4;
fid = fopen([mnl_data_path, 'packages.txt'], 'w');
a = num2str(z);
fprintf(fid,'%s\n',a);
for j = 1:1:z
    a = num2str(j);
    fprintf(fid,'%s\n',a);
end
fclose(fid);

Why isn't it printing to a new line?

Strange. I get each digit on a separate line, as you intend.

I am using the prerelease of R2012b, on a Mac running OSX 10.6.8.

Well I'm not sure what to do. It's definitely updating the file each time (if I change it to z = 5), I see "512345" printed to the text file.

Nevermind. When I open with notepad I see "41234". When I open with notepad++, I see

4 1 2 3 4

So I guess it is not Matlab, it is notepad.

Did you try View | Show Symbol | Show All Characters in notepad++?

Try wordpad. I think wordpad and notepad behave differently with regards to how they interpret \n and \r\n. You can know for sure what's there if you have access to an editor that can view in hex format.

Open the file with 'wt' instead of 'w'
