What you say doesn't really make sense. But I think you'll find what you're looking for with the fgetl() function. There's an example in the help there that should do what I think you want to do.
fid = fopen('fgetl.m');
tline = fgetl(fid);
while ischar(tline)
disp(tline)
tline = fgetl(fid);
end
fclose(fid);
