Write to txt, delimited by char(10)

Let

x = ['a' char(10) 'b'];

How can I print this to a text file say, test.txt, in such a way that it reads a in the first line and b in the second one?

x = ['a' char(10) 'b'];
fp = fopen('test.txt','w');
fwrite(fp,x);
fclose(fp);

I am on a Mac and using R2018b. That being said the above should work on all OS and most MATLAB releases.

There is also a command in MATLAB called newline (which is the same as char(10)

I've tried that, but it looks like this

So there is another way to do this:

x = sprintf('a\r\nb');
fp = fopen('test.txt','w');
fwrite(fp,x);
fclose(fp);

This has to do with your OS, and editor and how it interprets new lines.

char(10)

char(13)

Sometimes you would need both a \r\n for editors to recognize newline.

Yep, it was Microsoft notepad
