delete the new line character at the end when using dlmwrite

I have a binary matrix m by n (which contains either 0 or 1) and I want to write each column as a string to a file without any delimiter between characters. So, I have used

dlmwrite(file_name, A(:,i)', 'delimiter', '', '-append')

in a for loop. However, it appends a new line character after each write. How can I overcome this issue?

Thanks.

You cannot. Give up on using dlmwrite in a loop for that purpose.

If you are looping over all columns and not writing additional information then

dlmwrite(filename, A(:).', 'delimiter', '')

with no loop.
