Find corresponding Sympy, SciPy, mpmath, or NumPy function =========================================================== In the last section, we wrote ``Curl`` in Mathics3 and arranged and put it in a place where it would get loaded. However we only added forms for the two and three dimensional situations. We could go further and implement the other forms as well a SymPy search shows that ``Curl`` is a SymPy function as well: `sympy.vector.curl `_. Furthermore, SymPy understands coordinate systems, which is used in the last form. Next: .. toctree:: :maxdepth: 1 where
