v12 v13 44 44 || Using Data.Vector.Unboxed || 2.88 || [http://code.haskell.org/repa/repa-head/repa-examples/FFT/HighPass/legacy/vector/FFT.hs FFT.hs] || 45 45 || Using Jones's inplace C implementation || 0.24 || [http://code.haskell.org/repa/repa-head/repa-examples/FFT/HighPass/legacy/c/Jones.c Jones.c] || 46 || Using FFTW onEstimate mode || 0.09 || [http://code.haskell.org/repa/repa-head/repa-examples/FFT/HighPass/legacy/c/FFTW.c FFTW.c] ||46 || Using FFTW using Estimate mode || 0.09 || [http://code.haskell.org/repa/repa-head/repa-examples/FFT/HighPass/legacy/c/FFTW.c FFTW.c] || 47 47 48 48 The vector version uses the same radix-2 decimation in time (DIT) algorithm as the Repa version, but is not rank generalised. It applies a recursive 1d FFT to each row and then transposes the matrix, twice each.
