What's wrong in this code?

the assignment c = [c,a]; must be out of the else clause, but still inside of the while block.

Test	Status	Code Input and Output
1	Pass	n = 1; c_correct = 1; assert(isequal(collatz(n),c_correct))
2	Fail	n = 2; c_correct = [2 1]; assert(isequal(collatz(n),c_correct)) Assertion failed.
3	Fail	n = 5; c_correct = [5 16 8 4 2 1]; assert(isequal(collatz(n),c_correct)) Assertion failed.
4	Fail	n = 22; c_correct = [22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1]; assert(isequal(collatz(n),c_correct)) Assertion failed.
