error: z: =: nonconformant arguments (op1 is 1x1, op2 is 2x1)

My goal here is to use the "vector-function" y inside the function z which is itself used in G, to check that dG is the jacobian matrix of G (of course here is a simple example where it is useless to check, which is not the case of my real functions).
Here the variable for my jacobian is only the vector x, and y and z are side functions.
Can you help me, and explain me how to write properly what i want to do ?
