Remove DSP dependency

2

Removing DSP from FastTransforms reduces the load time from 3.7 s to 2.8 s for me, a 25% savings. @dlfivefifty, is there any downstream reason not to remove DSP?

I notice that `generic_fft` allows me to `fft` BigFloat, which is great! I found however that I couldn't do the usual thing with FFTW, e.g. ```julia generic_fft(X,2) ``` for only...

multidimensional nufft?

1

Hi, I noticed that 2D nufft’s of types I-I and II-II are mentioned in the [discourse](https://discourse.julialang.org/t/nonuniform-fast-fourier-transforms/4858/2) in 2017. As I looked at the code, it seems that the interface of...

I wonder if it would be realistic and/or a goal to make the library GPU compatible. With that I mean only the crucial part of applying a pre-computed plan to...
