There are no zero strings in your data. I assume you want to find out which are the same in the two files. You can do that easily enough by converting them to character arrays and using the intersect function:

fidi1 = fopen('Fateme Jalali t2.txt');
tt1 = textscan(fidi1,'%s', 'delimiter', '\n');
fclose(fidi1);
fidi2 = fopen('Fateme Jalali t3.txt');
tt2 = textscan(fidi1,'%s', 'delimiter', '\n');
fclose(fidi2);
tt1s = char(tt1{:});
tt2s = char(tt2{:});
[C,ia,ib] = intersect(tt1s,tt2s,'rows','stable');
