This namespace contains vector calculus operators, in versions built on top
of derivative/D and in Functional Differential Geometry style.
The former transform functions of scalars or vectors, while the latter take a metric and basis.

Curlclj/s
Operator that takes a function f and returns a function that
calculates the Curl of f
at its input point.
f must be a function from $\mathbb{R}^3 \to \mathbb{R}^3$.
Operator that takes a function `f` and returns a function that
calculates the [Curl](https://en.wikipedia.org/wiki/Curl_(mathematics)) of `f`
at its input point.
`f` must be a function from $\mathbb{R}^3 \to \mathbb{R}^3$.Divclj/s
Operator that takes a function f and returns a function that
calculates the Divergence of
f at its input point.
The divergence is a one-level contraction of the gradient.
Operator that takes a function `f` and returns a function that calculates the [Divergence](https://en.wikipedia.org/wiki/Divergence) of `f` at its input point. The divergence is a one-level contraction of the gradient.
divergenceclj/s
(divergence Cartan)(divergence metric orthonormal-basis)Both arities of divergence are defined on page 156 of Functional Differential Geometry.
Both arities of [[divergence]] are defined on page 156 of Functional Differential Geometry.
Gradclj/s
Operator that takes a function f and returns a new function that
calculates the Gradient of f.
The related [[D]] operator returns a function that produces a structure of the
opposite orientation as Grad. Both of these functions use forward-mode
automatic differentiation.
