DFFT23 * #include <unsupported/Eigen/FFT>
40 * half-spectrum for real FFT.
44 * We think the default behavior of Eigen/FFT should favor correctness and
51 * IFFT(FFT(x)) = Kx; this is done to avoid a vector-by-value multiply.
55 * How Eigen/FFT differs: invertible scaling is performed so IFFT( FFT(x) ) = x.
