Add Exponential of Semicircle Window

1

We want to integrate the "exponential of semicircle" window proposed in this paper: https://arxiv.org/abs/1808.06736 I am not completely sure but my FINUFFT wrapper indicates that it is slightly more accurate...

Implement NFCT/NFST

3

There are the real versions of the NFFT called NFCT and NFST: https://www-user.tu-chemnitz.de/~potts/nfft/fast_trig.php In my vision we can nicely put them together into `AbstractNFFT.jl` and `NFFT.jl`. To do this we...

Taken from #80: We want `p * f` to convert the vector `f` to the appropriate data type (e.g. `Float64` -> `ComplexF64`). This got removed during restructuring of the interface.

Benchmark Suite

2

I open this issue for discussions around the benchmark suite located here: https://github.com/JuliaMath/NFFT.jl/tree/master/benchmark The results are automatically integrated into our documentation https://juliamath.github.io/NFFT.jl/dev/performance/ My idea would be to have a quick...

Inconsistency between 1D NFFT and (N,1)-dimensional NFFT

3

The result of a 1D NFFT of length N and a (N,1)-dimensional NFFT are quite inconsistent. Here is a MWE: ``` using NFFT M = 4 x1 = collect((-Int(M/2)):(Int(M/2)-1))/M N1...
