I played with Enzyme a little bit, and I suspect it's not ready for use with our package. It can't differentiate simple ODEs at present. There's a fair amount of linear algebra in OrdinaryDiffEq, so i…

An effort to create a very simple Decapode, to help simplify diagnosing autodiff through decapode issues.
This is a 1-D harmonic oscillator Decapode:

Leslie and I realised that a quite useful enhancement would be a new interface that computes directional derivative w.r.t. NU source or target locations. This would involve a few more spread/interp fl…

I define the function f(x) = x*(1-x^(1.1)). It is twice differentiable at x=0. Above that, not. At live.sympy.org I did:
```
>>> gamma = 1.1
>>> for n in range(10): print(n, diff(x*(1-pow(x, gamm…
