divergence in cylindrical coordinates

I have a vector field in axisymmetrical cylindrical coordinates composed of u_r and u_z. Is there a function in matlab that calculates the divergence of the vector field in cylindrical coordinates? I know that the function 'divergence' calculates for a 2D field.
