MATLAB: Matching two texts

Question

Hi,

I have two texts . is it possible to extract the text where the two arrays match.For example: A='First Boston Corp Lehman Brothers ' B='Lehman Brothers Merill Lynch'; How can I get the match "Lehman Brothers"

Answer 1

The simple brute force method:

A='Lehman Brothers Merill Lynch'; 
B='First Boston Corp Lehman Brothers';
for n = 1:numel(B);
    for k = 1:n
        if ~isempty(strfind(A,B(k + (0:numel(B)-n))))
            Bmatch = B(k + (0:numel(B)-n))
            return
        end
    end
end
