Description
Since PR #58 is now merged, I would suggest talking about how to extend this to Plans
as well.
One way of doing that would be to implement different (abstract) types for a FFT, rFFT and r2r. This of course would have some implications for the libraries relying on AbstractFFTs. That's why I did not directly proceed with a PR, but would want to discuss this first.
Something reasonable could be to have an AbstractFFTPlan
, AbstractrFFTPlan
, AbstractR2RPlan
that are all subtypes of the current Plan
type, so that it is not a completely breaking change. (Ideally Plan should be renamed to AbstractPlan, but this would break a lot, I guess)
Aside from this, there is also JuliaMath/FFTW.jl#182 , so that ScaledPlans miss the region
subfield, which could be mitigated by a function like
region(p::Plan) = p.region
region(p::ScaledPlan) = region(p.p)
