I would like to use fprintf to save the following line as a text file.

%%number of points: x

x is a variable and for instance x=25

%%number of points: 25

thank you very much

And what aspect of it is causing you a problem?

I do not know how to write it

fid=fopen('your_file.txt','w')
x=25
str=sprintf('number of points: %d',x)
fprintf(fid,'%s',str)
fclose(fid)

I would just go for

fid = fopen('your_file.txt', 'w');
x = 25;
fprintf(fid, '%%%%number of points: %d\n', x);
fclose(fid);
