Move Chebyshev functionality to Chebyshevtransforms.jl #186
Description
So, I’ve rewritten the Padua transform code with extensive testing and documentation and have it registered over at ChebyshevTransforms.jl here in JuliaApproximation. I think it would make sense to transition more of the Chebyshev functionality from FastTransforms and other packages over there and then reexport here and elsewhere.
I also saw that there are multiple Julia packages doing various versions of Chebyshev polynomials. We might try to unify them here at JuliaApproximation. I might need Chebyshev polynomials for my Master’s thesis, in which case I could get started on this project.
Here are the packages I’m aware of that have functionality we might want to unify.
- FastChebInterp.jl
- ChebyshevApprox.jl
- FastTransforms.jl and ClassicalOrthogonalPolynomials.jl
It may be these packages tackle fundamentally different use cases. In any case, the future of Chebyshev transforms in Julia seems worth discussing.
