finding carriage returns (i.e. \n) in a text file

Hi all, I have a text file with carriage returns in it, and am trying to test if an index is a carriage return but have been unsuccessful. For simplicity, lets say that the text file only uses \r as a carriage return. I understand that isstrprop(text(index),'wspace') can identify if it is a space OR a carriage return, but I want to check only to see if it is a carriage return.

Any advice? Let me know if I can be any clearer here.

Thank you so much in advance, William

See if this does what you want:

Q = sprintf('This is a string \r with a newline character.\r');

NL = regexp(Q, '[\r]');

The ‘NL’ variable contains the indices of the occurrences of '\r' in the string.

YourString == sprintf('\r')

or

YourString == char(13)

Note: char(13) is \r the carriage return. Your description uses the word carriage return but uses \n which is newline, char(10) . You need to decide which you are looking for. If you are looking for either, then

ismember(YourString, char([10 13]))

My pleasure!

They’re fun for me — I probably learn as much as I contribute.
