Hi,

I am trying to find palindromes and near palindromes within
text strings using regular expressions. I used a regexp from
the Matlab help to get

test = 'aaaaCDEFGGFEDCbbbbbJKLMNOaabbONMLKJaaaa';
P = regexp(test,'(.{3,13}).?(??@fliplr($1))','match');

which correctly gives P = 'CDEFGGFEDC'.

I would also like to be able to find the near palindrome
starting with JKL. By near palindrome I mean something like
JKLMNOaabbONMLKJ where the aabb part may be two or more
nonpalindromic characters. Unfortunately, I think my regular
expression Kung Fu is too weak to see how to do that. Anyone
out there know a simple way to do this?

Thanks,
J
