Re: [eigen] fft module status

[Mark Borgerding <mark@xxxxxxxxxxxxxx>]

You are correct in your assessment.  The MKL backend and 2-D FFTs are 
still TODO.
I updated the status page and put a link to the EigenFFT wiki page to 
clarify this.

Please feel free to opine (here or on the wiki discussion page) which 
ranks higher in priority: MKL backend or multi-dimensional FFTs. 

FYI, If you want to use MKL as a backend before I get around to writing 
it (probably within a month), you can make the intel MKL fftw3xc 
interface that comes with it.  Then tell Eigen::FFT that it should use 
FFTW as a backend.  This would allow the advantages of MKL with the 
current state of the code.
