Warning-documentation files not found

I have reinstalled matlab 2013b on my laptop, but it shows "Warning-Documentation Files not Found" as seen below When I entered some doc command, such as 'doc plot'. How can I make it working properly?

I'm having this same problem. No documentation after installing 2013b on Mac OSX 10.9.

Perhaps this question and answer are applicable for you, too. I don't know for sure, though.
