2   Fail
n = 2; c_correct = [2 1]; assert(isequal(collatz(n),c_correct))

c = 2

The end operator must be used within an array index expression. Error in collatz (line 3) while C(end)~=1 Error in Test2 (line 3) assert(isequal(collatz(n),c_correct))

3   Fail
n = 5; c_correct = [5 16 8 4 2 1]; assert(isequal(collatz(n),c_correct))
