ForwardDiff

[ioannisPApapadopoulos]

I think the following used to work. Any ideas @TSGut @dlfivefifty ?

using SemiclassicalOrthogonalPolynomials
import ForwardDiff: derivative

julia> derivative(x -> SemiclassicalJacobi{eltype(x)}(1.1,1,1,1)[x,1], 0.5)

Are you using FastTransformsForwardDiff.jl? (This should be changed to an extension)

[ioannisPApapadopoulos]

Ah, thanks for the pointer! I will have a look.

[ioannisPApapadopoulos]

Unfortunately FastTransformsForwardDiff.jl does not work either. Seem the issue is with plan_cheb2jac

ERROR: MethodError: no method matching plan_cheb2jac(::Type{ForwardDiff.Dual{ForwardDiff.Tag{var"#15#16", Float64}, Float64, 1}}, ::Int64, ::ForwardDiff.Dual{ForwardDiff.Tag{var"#15#16", Float64}, Float64, 1}, ::ForwardDiff.Dual{ForwardDiff.Tag{var"#15#16", Float64}, Float64, 1})

[ioannisPApapadopoulos]

I'm on FastTransforms v0.15.6 if that would make any difference.

[TSGut]

Is this break recent? I.e. did the recent semiclassicalops changes break it?

I don't know if we ever got around to cheb2jac. You just need to add the overloads: FastTransformsForwardDiff.jl is only 50 lines of code so you should be able to adapt it to other transforms. There's no mathematics to work out: linear operators just apply to the real and dual operators seaprately
