Hi! I have the string s1 and s2

s1={'1' '631' '618' '574' '678'} 
s2={'1' '596' '674' '' '';'674' '631' '1' '631' '1';'641' '617' '674' '631' '654';'674' '673' '674' '673' '674';'674' '618' '1' '618' '631';'631' '1' '631' '674' '740';'739' '740' '733' '674' '631';'674' '673' '674' '1' '641';'618' '1' '631' '618' '631';'674' '631' '618' '631' '618';'674' '631' '1' '631' '625';'641' '642' '618' '631' '618';'618' '631' '1' '631' '1'}

I want to compare s1 and its substrings

{'1'}
{'1' '631'}
{'1' '631' '618'}
{'1' '631' '618' '574'}
{'1' '631' '618' '574' '678'}
{'631'}
{'631' '618'}
{'631' '618' '574'}
{'631' '618' '574' '678'}
{'618'}
{'618' '574'}
{'618' '574' '678'}
{'574'}
{'574' '678'}
{'678'}

with s2: I have used strcmp(s1,s2) but I don't obtain the expected result. Can you help me?

s1={'1' '631' '618' '574' '678'} ;
s2={'1' '596' '674' '' '';
     '674' '631' '1' '631' '1';
     '641' '617' '674' '631' '654';
     '674' '673' '674' '673' '674';
     '674' '618' '1' '618' '631';
     '631' '1' '631' '674' '740';
     '739' '740' '733' '674' '631';
     '674' '673' '674' '1' '641';
     '618' '1' '631' '618' '631';
     '674' '631' '618' '631' '618';
     '674' '631' '1' '631' '625';
     '641' '642' '618' '631' '618';
     '618' '631' '1' '631' '1'} ;
[m,n] = size(s2) ;
comp = zeros(size(s2)) ;
 for i = 1:m
     comp(i,:) = strcmp(s1,s2(i,:)) ;
 end

Compare each row of s2 with s1.
