have a problem to find the similarity of two patterns. I use LCS of this two pattern to represent their longest common part. For example given a pattern
P='012(32)231(43)'
and a pattern
Q='231(43)40(12)321'
their longest common sequence is
LCS(P,Q)= '0,1,2,3,4,(43)'
I want to find similarity of 106 strings in a cell array. The common elements are the number (0,1,2,3,4) or couples of number that both strings have (43). I have a lot of difficultes: I have no idea, I can do it. I have found in MATLAB functions like strcmp, strcmpi, strncmp, strncmpi, ismember but they are for strings of same size; I have thought about using regexp but I don't know how. I have read other questions about compare strings but none appears to address this problem. Can you give me suggestions?

Are you looking for common subsequences or common substrings?
