Try this:
fid = fopen('ny.txt','wt');
fprintf(fid, 'Happy\nNew\nYear');
fclose(fid);

Or, if your strings are in variables,
fid = fopen('ny.txt','wt');
fprintf(fid, '%s\n%s\n%s', string1, string2, string3);
fclose(fid);

hi, if you use latest matlab 2022a， you can use new matlab build-in function WRITELINES

The correct one is
fid = fopen('ny.txt','wt');
fprintf(fid, 'Happy\n');
fprintf(fid, 'New\n');
fprintf(fid, 'Year\n');
fclose(fid)
Anyway, so many thanks for your great help.

How i can write extracted text in text file

Is there a way to use save function to do that simple job? I could never get why an intuitive write in matlab needs such an un-intuitive function F-Print-F.

That's just the name of it. It matches the name used in other languages like C, Java, etc. The save() function does not write custom formatted strings out to a text file like fprintf() does. The save() function saves variables in a binary, proprietary fashion.

Thanks for the comments. Save has a -ascii option which is supposed to do what I need. But now that you know about matlab, could you please comment on my question here: write multiple lines of text into a text file ?

"Each variable must be a two-dimensional double array."
Character strings are not double array. double() of the string is done internally and that is written, getting back results such as
1.0400000e+02 1.0100000e+02 1.0800000e+02 1.0800000e+02 1.1100000e+02 9.2000000e+01 1.1000000e+02 1.1900000e+02 1.1100000e+02 1.1400000e+02 1.0800000e+02 1.0000000e+02
for 'hello\nworld'
