It would be helpful, if you explain the input. It matters, if you are reading a text file under Windows or getting data from a serial port under Linux.

If you have the file open in text mode, then end of line occurs when the character you read in is newline, char(10), sprintf('\n')
If you do not have the file open in text mode, then end of line is whatever that particular binary format says end of line is.

Why do you say you don't need fgetl() when that seems to be the solution to your problem?

You may not need to. Are you aware that you can read to the end of a line with built in functions fgets() and fgetl()?
fgets: Read line from file, keeping newline characters
fgetl: Read line from file, removing newline characters

It won't work if you read in each string one-by-one, you have to read in each character one-by-one for it to work.
fid = fopen('filename.txt','r');
char_temp = fscanf(fid,'%c',1);
while ~isequal(char_temp,sprintf('\n'))
char_temp = fscanf(fid,'%c',1);
end
disp('Have reached end of line');
OR...
fid = fopen('filename.txt','r');
char_temp = fscanf(fid,'%c',1);
while ~isequal(char_temp,char(10))
char_temp = fscanf(fid,'%c',1);
end
disp('Have reached end of line');
Now that we know you are working with numbers...
fid = fopen('filename.txt','r');
while ~feof(fid)
temp_str = fgetl(fid);
c = sscanf(temp_str,'%d');
% do things with "c"
end
fclose(fid);
