out = any(ismember(a.*a, a))

Test	Status	Code Input and Output
1	Pass	a = [2 3 4]; assert(isequal(isItSquared(a),true))
2	Pass	a = [20:30]; assert(isequal(isItSquared(a),false))
3	Pass	a = [1]; assert(isequal(isItSquared(a),true))
4	Pass	a = [6 10 12 14 36 101]; assert(isequal(isItSquared(a),true))
5	Pass	a = [6 10 12 14 101]; assert(isequal(isItSquared(a),false))
