Research direction

Start by reviewing the linked FFTW.jl pull request and the AbstractFFTs.jl interfaces related to real-to-complex transforms. Clarify whether AbstractFFTs should expose an in-place real-to-complex rfft! API, including the expected data layout and CuFFT compatibility; done requires agreement on the interface and corresponding implementation coverage.

Written by the indexing model from the issue text.

Description

Hi,

since there is a PR for rfft! in FFTW we probably should also add rfft! in AbstractFFTs?

In general in-place real-to-complex FFT seems to be supported by CuFFT as well, right?

I recall that I was discussing this somewhere with @maleadt but I can't remember exactly.

What do you think about that?

Best,

Felix
