I have the following code. I am not sure why the newline is not creating a new line. I use dlm write to write out footer to a '.env' file. But I don't think that makes a difference.

footer = ['''A'' 0 \n'];
footer = [footer, num2str(depth_bottom) ' ' num2str(avg_ssp) ' ' num2str(0) ' ' num2str(1) '\t/\n'];

This is the output I am getting.

>> footer
footer =
    ''A' 0 \n5000 1600 0 1\t/\n'

The actual output should be:

'A' 0  
5000.0 1600.00 0.0 1.0

So the output you are getting is

footer = ['''A'' 0 \n'];
footer = [footer, num2str(depth_bottom) ' ' num2str(avg_ssp) ' ' num2str(0) ' ' num2str(1) '\t/\n'];

but you were expecting to get

'A' 0  
5000.0 1600.00 0.0 1.0 

??? That's what you said. How are you calling dlmwrite()? I don't know why it would say "footer = ...." unless you somehow told it that "footer = ....." was in the header lines you told it to use.
