WeightedSemiclassicalJacobi vs. Weighted(SemiclassicalJacobi)

[ioannisPApapadopoulos]

@TSGut @dlfivefifty

Currently this works:

a=1; b=1; c=0; t=1.2; WeightedSemiclassicalJacobi(t,a-1,b-1,c+1/2) \ WeightedSemiclassicalJacobi(t,a,b,c+1/2)

but the following gives the error:

a=1; b=1; c=0; t=1.2; Weighted(SemiclassicalJacobi(t,a-1,b-1,c+1/2)) \ Weighted(SemiclassicalJacobi(t,a,b,c+1/2))

ERROR: ArgumentError: Override copy for Weighted{Float64, SemiclassicalJacobi{Float64}} \ Weighted{Float64, SemiclassicalJacobi{Float64}}

I am not quite sure where to add the copy. Moreover, the Ldiv is defined for WeightedSemiclassicalJacobi and not Weighted(SemiclassicalJacobi) in lines 324-347 of https://github.com/JuliaApproximation/SemiclassicalOrthogonalPolynomials.jl/blob/master/src/SemiclassicalOrthogonalPolynomials.jl. Should this be updated?

Ah ok for now maybe just add

\(w_A::Weighted{<:Any,<:SemiclassicalJacobi}, w_B::Weighted{<:Any,<:SemiclassicalJacobi}) =
     convert(WeightedBasis, w_A) \ convert(WeightedBasis, w_B)
