It's about time you learned some basic principles on how to ask questions after more than 70 question...

Please show the code you are using to open and scan the data. The method to check for end of line will depend on the details of your existing code.
MATLAB as a language does not recognize "escape sequences" such as \n and \t in strings (this is unlike C.) Instead, those sequences are recognized directly by the routines that deal with formatting strings, such as fscanf() and fprintf().
newline is generally coded either as char(10) or as sprintf('\n') but we will need to see what you have already to know whether either of those would be appropriate for your situation.

hi,
this is code:
k1=1;
for i=1:7000
k=1;
for j=1:???? unknown (length of columns is different)
celcod{i,k}=z(k1:k1+3);%%%each three symols be one cell
k=k+1;
k1=k1+4;
end
end
I need to check new line in the second loop.
this is sample of my file

That does not show the code to open or scan the data. I am looking for the fopen() and fscanf() calls and anything else that you do with the file.
