114 If you have a real data input data[] of size 2**(log2Size + 1), you
122 Fourier transform of a real data input, you can also conduct the inverse
123 Fourier transform to get the real data input by
145 500 runs of paired 256 point complex (512 point real) input FFT

255 do_real_fft conducts a forward FFT of a real data array using
262 data -- A real data array, overwritten by the positive frequency
266 even elements store the real component, while the odd
275 do_real_ifft conducts an inverse FFT of a real data array's FFT using
282 data -- FFT of an real data array, overwritten by the real data array.
285 the even elements store the real component of the transform,
