Missing show method for SemiclassicalJacobi #103

Closed DanielVandH closed 2 months ago

DanielVandH commented 2 months ago

There is no show method defined for SemiclassicalJacobi which causes issues when string interpolation is required, e.g. the print method for Weighted requires it:

julia> using SemiclassicalOrthogonalPolynomials, ClassicalOrthogonalPolynomials

julia> P = SemiclassicalJacobi(2.0, 1.0, 1.0, 1.0);

julia> W = Weighted(P);

julia> W
Error showing value of type Weighted{Float64, SemiclassicalJacobi{Float64}}:
