Regexp question number two

Asked by Lucas on 19 Sep 2012

I have no idea why this isn't working. I've read in several places that this should work, but it doesn't. I have a string like:

str = 'Hello\nMy name is Lucas';

and I wanted to use regexp to split at the new line character, so I have the following:

results = regexp(str, '\n', 'split');

but it doesn't split the string and just returns the original string. I just upgraded to 2012b. Thanks.

Accepted answer

You need to escape the `\`

 results = regexp(str, '\\n', 'split')

To (hopefully) clarify: the "\n" in your string isn't actually a newline character -- it's just the two characters \ and n. So Daniel's solution is splitting on the literal combination of characters "\n".

If you had defined your string as

str = ['Hello',10,'My name is Lucas']

then the 6th character would actually be a line break and your regexp command would have worked.
