Hello, I wonder if anyone knows a package which implements a fft in multiple dimensions for arbitrary precision number (BigFloats).
I have not found any but I could imagine it exists.
It seems like FastTransforms.jl has this, but doesn’t document it anywhere:
You might want to open an issue about maybe documenting it a bit better. (Or even contribute docs yourself once you’ve figured out how it works.)
But it looks to me as it were only in 1d.
Ah, I see! I don’t know whether there’s anything for that then.
