sdc function does not work for directional nfft

1

```julia using NFFT, NFFTTools J = 11 y = rand(J) .- 0.5 N = (16,20) p1 = plan_nfft(y, N, dims=1) f = randn(ComplexF64, N) fHat = p1 * f w=sdc(p1)...

copying of CUDA Plan does not work

4

Sorry for spamming :laughing: But copy of a CUDA plan does not work: ``` p = NFFT.plan_nfft(coords, (size(x,1), size(x,2))) MethodError: no method matching copy(::CuNFFT.CuNFFTPlan{Float32, 2}) Closest candidates are: copy(!Matched::LinearAlgebra.Hessenberg{

Disable Threading for NFFT | does not work and produces `NaN`s

Hi! I wanted to disable threading such that I can calculate the NFFT along the first two dimensions, and loop myself along the third dim. The for loop should be...

`dims` argument for multidimensional NFFT

4

Hi! I didn't find a `dims` kwarg to perform an NFFT along first and second dimension of a 3D array. Is there any? Especially on GPUs that's usually faster than...

Implement NNFFT

I added the NNFFT in AbstractNFFTs but actually `NFFT.jl` is missing an implementation. So this is the feature request issue.

Non-deterministic GPU results

I've got a case where subsequent (adjoint) NFFTs on GPU are giving different results. I don't have a MWE yet but just to prove it:  Is...

Implement Autotuning of Kernel Size and Oversampling Parameter

2

Right now NFFT.jl gives the user no hint on how to chose the kernel size and the oversampling parameter. This was on purpose since I don't want too much "magic"...

Suggestion: infer plan type from `x` type

8

If I understand correctly, the current approach is that user decides between cpu and gpu versions by either * CPU: `p = plan_nfft(x, N)` or (currently equivalently I think) `p...
