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?

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.
