I’ve only been playing with MTK.jl for a day or two, but I’m really impressed - the workflow here is so much nicer than using a dedicated acausal modelling language! I’m running into situations where judicious function registration is advisable, and I’d like to understand how flexibly derivatives ca…

i think you need to generate a wrapper function around the ForwardDiff.derivative function and use that instead: AD_derivative(f,x) = ForwardDiff.derivative(f,x) foo_f3(x) = x^2 @register_symbolic AD_derivative(f::Function,x) @register_symbolic foo_3(x) Symbolics.derivative(::typeof(foo_f3), args::…
