a function that return two string's largest common part

Description

a function that return two string's largest common part

% Usage:
% [ret]=LCSubstr(s,t)
% s: input string 1
% t: input string 2
% ret: Largest Common String
% z: Largest Common String Length
% L : Compare matrix
% Example:
% >>a='This is very common string';
% >>b='string is very common';
% >>[ret]=LCSubstr(a,b)
% ret =
%

Just what I was looking for! Thanks! 好工作

I believe the name of this function is miss-leading. The Longest Common Substring for the example given is "is very common". Also.... LCS I believe should return the string minus characters. For example, the LCS of [1, 2, 3, 4] and [1, 2, 2, 4] is [1, 2, 4]. This function only returns [1, 2].
