How can I write both number and text to a file?

I want to write something like this:

BEGIN 0.00 0,0 0.5,1 1,1.5 1.5,1.75 14,2

from matlab to a text file. There are supposed to be a new number on one line, going down. I also have to go this several times for different values. How can I do this effectively?

The easiest way to do this would be to write the entire line as a string into a text file, something like:

 x = 'BEGIN 0.00 0,0 0.5,1 1,1.5 1.5,1.75 14,2';
 fid = fopen('SomeTextFile.txt','a');
 fprintf(fid,'%s\n',x);
 fclose(fid);

You would have to reassign x every time with your new data. Does this help?

Yes, Thank you!

This thing doesn't print anything. Try adding file identifier in the fprintf command..

fprintf(fid,'%s\n',x);

My bad! I corrected it.

Look here:

https://it.mathworks.com/help/matlab/ref/fprintf.html

Here it is:

x = 'BEGIN 0.00 0,0 0.5,1 1,1.5 1.5,1.75 14,2';
 fid = fopen('SomeTextFile.txt','a');
 fprintf(fid,'%s\n',x);
 fclose(fid);

But, for more complex inputs I suggest to read the help page. Will be useful.
