that gives me an array as an answer (and does more calculations than
necessary, in this case 9 instead of 3). The result should be a vector.

The function should work on the nth elements of the two input vectors
and put the result into the nth element of the output vector. So it
would work like c <- a + b, only instead of '+' there are more complex
calculations.

Best regards,
