fprintf: writing a cell array to a text file

Question

I have a cell array of strings called myarray, containing n elements. I want to write the array to a text file called myfile.txt. I want every line in the text file to correspond to one element in the cell.

When I try the following:

fid = fopen('myfile.txt', 'w');
for i=1:n
    fprintf(fid, '%s\n', myarray{i});
end

However, this outputs a file without any carriage returns after each element. When I open it in Notepad in Windows, I see just a list of characters which is from the strings in myarray concatenated together. However, I want each string to be on its own line.

What's going on?

With NotePad you might want to use '\r\n' instead of '\n'. Hence:

fid = fopen('myfile.txt', 'w');
for i=1:n
    fprintf(fid, '%s\r\n', myarray{i});
end

I can't test it right now though. Take a look at this:

Taken from the Matlab help:

Some Windows® text editors, including Microsoft® Notepad, require a newline character sequence of '\r\n' instead of '\n'. However, '\n' is sufficient for Microsoft Word or WordPad

You have two options.

Stop using stupid software, use any other text editor and you will see the new line
Use carriage return and line feed
