The background is CODY problem 95
The purpose is to confirm whether the vector s1 contains the vector s2. (or s2 cover s1)
The problem is that when the size of the vector is very large, the function ’contains‘ cannot be judged correctly.
case 1
clear

s1 = 1:100;
s2 = [50 51];

s1str=num2str(s1);
s2str=num2str(s2);
tf1=contains(s1str,s2str)
tf2=contains(s2str,s1str)
tf1 SHOULD be 1, since [50 51] is part of s1. but the result is not correct.
case 2
s1 = 40:60;
s2 = [50 51];

s1str=num2str(s1);
s2str=num2str(s2);
tf1=contains(s1str,s2str)
tf2=contains(s2str,s1str)
When the size of the vector S1 decreases, the function works normally.The background is CODY problem 95
