Say a=[4 5 8 9 4], How to detect this set has repeated numbers? I do not want to know the number, I just want to know that "a set has repeated numbers or not"

Check unique. If the length of your array and length of unique are not same it has repeated numbers.
a=[4 5 8 9 4] ;
b = unique(a) ;
fprintf('array has repeated numbers\n')
fprintf('array has no repeated numbers\n')
