Since this is probably a common thing, I feel like there should be a section in the documentation for properly linking against LAPACK/BLAS. For example, I developed a binary package...

@rewrite for arbitrary operation/function

Does MutableArithmetics not work for general functions, only for the standard arithmetic operations (+,-,/,*)? I have a mutable type that overrides many of the Base functions (sin, cos, abs, sqrt,...

```julia using ForwardDiff using Diffractor: DiffractorForwardBackend import AbstractDifferentiation as AD function test(z0) z = Vector{eltype(z0)}(undef, length(z0)) L = 0.5 k1 = 0.36 z[1] = cos(sqrt(k1)*L)*z0[1]+1/sqrt(k1)*sin(sqrt(k1)*L)*z0[2] z[2] = -sqrt(k1)*sin(sqrt(k1)*L)*z0[1]+cos(sqrt(k1)*L)*z0[2] return z...

Documentation needs to be added

It is an uphill battle figuring out how to implement this interface. The only documentation I can find on how to do so is hidden in [this paper](https://proceedings.juliacon.org/papers/10.21105/jcon.00093), but even...

#316

Adding `GTPSA.jl` to the interface

15

I'll use this issue for questions I have for implementing this interface into [`GTPSA.jl`](https://github.com/bmad-sim/GTPSA.jl). I've done some reading of the documentation and those AD packages in `ext`, and here are...

Error when using `map` on `FieldVector` of `Vector`

1

Consider the struct ```julia struct Coords{T} c = Coords([1,4],[2,5],[3,6]) 3-element Coords{Int64} with indices SOneTo(3): [1, 4] [2, 5] [3, 6] ``` Now say we'd like to get the first coordinate...

`similar` when called with a `FieldVector` should output an array type equal to the input type (with possibly different `eltype` if specified). However the current behavior does not do this....

Mutable quaternion?

10

My organization has a need for a mutable quaternion. We really like this package as a lightweight, fast quaternion implementation for simulations, and we were wondering if a PR would...
