Hi, I do not know FFT in depth. I just need a fast, open source inverse FFT implementation. I have tested 3 implementations:
1. Math.NET Fourier.Radix2Inverse : the slowest for the small data (1024…

both the functions `fourier_transform` and `_fourier_transform` give the (same but) wrong result, when applied to the function `sin(x)**2/x**2`. Here is the sample code:

## Basic MORF implementation
Need to implement:
1. Cython splitter: Patch splitter (discontiguous and contiguous)
2. Cython tree: I think we don't even need a new Cython tree. We can just use t…

Hi,
This is not really an issue. I am wondering if the following is expected to allocate:
```julia
julia> F = zeros(31,61);
julia> PS = FastSphericalHarmonics.plan_sph_synthesis(copy(F))
Fa…
