Triangle examples in examples/triangleexamples.jl fail

5

The examples [here](https://github.com/JuliaApproximation/MultivariateOrthogonalPolynomials.jl/blob/master/examples/triangleexamples.jl) fail (below is Lines 1-12 from that file) ```julia julia> using ApproxFun, MultivariateOrthogonalPolynomials, BlockArrays, SpecialFunctions, FillArrays, Plots import ApproxFun: blockbandwidths, Vec, PiecewiseSegment import MultivariateOrthogonalPolynomials: DirichletTriangle S =...

In response to #176, this PR adds an extra check that all the example scripts actually run by simply including them one at a time inside the tests. Currently, these...

CompatHelper: bump compat for FastTransforms to 0.16, (keep existing compat)

1

This pull request changes the compat entry for the `FastTransforms` package from `0.15.11` to `0.15.11, 0.16`. This keeps the compat entries for earlier versions. Note: I have not tested your...

Jp/zernike partials

3

I managed to implement the partial derivatives with respect to y. The following code now runs: `using MultivariateOrthogonalPolynomials W = Weighted(Zernike(1)) Δ = Laplacian(axes(W,1)) ∂ʸ = PartialDerivative{2}(axes(W,1)) Z⁰ = Zernike(0)...

JacobiTriangle() expansions failing in strange way

2

There is some strange behavior when expanding functions on triangles, apparently when it comes to globally defined variables? Here is a minimal example: ```julia julia> using MultivariateOrthogonalPolynomials julia> T =...

Lowering bug?

8

@dlfivefifty The lowering `Zernike(0,1) \ Weighted(Zernike(0,1))` is a factor of 2 off. This also seems to be confirmed in the tests..? https://github.com/JuliaApproximation/MultivariateOrthogonalPolynomials.jl/blob/cb0fb241eecc49fbdb873a5cd2b7de098897d355/test/test_disk.jl#L303 Is there a reason for this?

Missing triangle functionality (Laplacian, restriction)

2

Am I correct in believing that the Laplacian and edge restriction operators on the triangle have not been implemented in the ClassicalOPs version? I distinctly remember that functionality working in...

Ridge polynomials (on the disk)?

2

These look like `P_{n,k}(x,y) = U_n(x * cos(k*pi/(n+1)) + y * sin(k*pi/(n+1)))`, orthogonal on the unweighted unit disk. Sparse differentiation is trivial (using ultraspherical generalizations), but the Jacobi operators are...
