hello,I have two text files including 100 lines.I want to compare same lines in two texts. for example line 1 from text 1 with line 1 in text 2 and line 2 in text 1 with line 2 in text 2 and ... I wrote this code but it compares all lines in text 1 with all lines in text 2.can any one help me to write correct codes?thanks.

    fidi1 = fopen('part11.txt');
tt1 = textscan(fidi1,'%s', 'delimiter', '\n');
fclose(fidi1);
fidi2 = fopen('part22.txt');
tt2 = textscan(fidi2,'%s', 'delimiter', '\n');
fclose(fidi2);
tt1s = char(tt1{:});
tt2s = char(tt2{:});
[C,ia,ib] = intersect(tt1s,tt2s,'rows')%Find set intersection of two vectors.
common_parts = size(C,1);

Fateme Jalali you did not answer my questions about what you want to do if they match or if they do not match, and about whether you need to worry about missing lines.
