Fourier{BigFloat}

6

Is there a way to work with Fourier and BigFloat? It goes via FFTW which is causing some issues. ``` using ClassicalOrthogonalPolynomials F = Fourier{BigFloat}() F[:, 1:10] \ sin.(axes(F,1)) ```...

I've submitted a PR to QuantumOptics.jl which replaces it's own implementation of Hermite polynomials with this package (https://github.com/qojulia/QuantumOpticsBase.jl/pull/137). However adding ClassicalOrthogonalPolynomials as a dependency caused the Aqua tests for ambiguities...

How to get BigFloat accurate conversion operators?

4

For OPs on `y⁴ = 1 - x⁴` I need conversion operators between `ChebyshevT()` and certain semiclassical OPs, e.g., ```julia T = ChebyshevT{BigFloat}() x = axes(T,1) P₁ = LanczosPolynomial( (1...

Laguerre Derivatives

6

@dlfivefifty Is there a reason why the LaguerreWeight axis was originally all of R rather than just the HalfLine?

ioannisPApapadopoulos

Seems to happen specifically for normalized polynomials. This works: ```julia julia> P = Jacobi(0,1) Jacobi(0.0, 1.0) julia> P'P ((inv(ℵ₀×ℵ₀ LazyBandedMatrices.Bidiagonal{Float64, LazyArrays.BroadcastVector{Float64, typeof(/), Tuple{InfiniteArrays.InfStepRange{Float64, Float64}, InfiniteArrays.InfStepRange{Float64, Float64}}}, LazyArrays.BroadcastVector{Float64, typeof(/), Tuple{InfiniteArrays.InfStepRange{Float64, Float64},...

How to cite the package?

4

@dlfivefifty What's the preferred way to cite this package as well as others in its ecosystem such as https://github.com/JuliaApproximation/ContinuumArrays.jl and https://github.com/JuliaApproximation/QuasiArrays.jl ? I want to specifically refer to these packages...
