Hello,
I looked at the unsupported FFT(W) implementation in eigen.
I like the concept of the plan and execute approach implemented.
However I have the impression that the code is not finished.
Can someone comment on the state of the implementation?

`Also I wonder how to create the arrays for fftw. It requires aligned
``arrays
``for fast computation. The eigen/fft code itsself does not use the
``fftw_malloc functions.
`

`The example uses plain vector<complex<float> > which is possible but
``might not allow
`fast computation.
Eigen::FFT<float> fft;
std::vector<float> timevec = MakeMyData();
std::vector<std::complex<float> > freqvec;
fft.fwd( freqvec,timevec);
// manipulate freqvec
fft.inv( timevec,freqvec);
In FFT I was wondering the use of "fft_fwd_proxy"
I see no example code nor do I understand its usage.
I am interested in the code mainly because I have my own fftw-cpp class

`and I consider to reuse the fft-code from eigen and publish it
``independed of eigen.
`
