Eigen is great. Thanks to everyone who has done so much work on it.
I've written a complex fft algorithm for eigen. It uses template metaprogramming, and is fairly snappy.
Are you sure that it matches in performance with the FFTW Libary? I just say that because I personally would use eigen for matrixes and FFTW for FFT. But maybe you can convince of the improvements of you solution compared to mine. The first that would come to my mind is, that FFTW requires a plain 1D C-Array for a Matrix (of 2 or 3 dimensions).
