We have a basic version of
Curl. There is more that could be done though:
Add unit tests using
Extend to the other forms of Curl, possibly using SymPy
There is however one last step that we will do here: note that we have added this builtin function.
The place to do this is in CHANGES.rst.
Find the section lablewed New Builtins` at the top of the pages and add this function. As we saw for adding classes, please add the name in alphabetic order.
Here is a "diff" after we added this function: diff --git a/CHANGES.rst b/CHANGES.rst index 23a37db0..ec80c087 100644 --- a/CHANGES.rst +++ b/CHANGES.rst @@ -11,6 +11,7 @@ New Builtins #. ``$BoxForms`` #. ``ClebschGordan`` +#. ``Curl`` (2-D and 3-D vector forms only) #. ``Kurtosis`` #. ``PauliMatrix`` #. ``SixJSymbol``
