WEBThe reference output is computed now (before calling fftw_execute), since in some later examples (most notably multi-dimensional c2r transforms), FFTW overwrites the input data and for good practise, we keep this in mind already now. Note that this is an out-of-place transform, since in and fftw_out are allocated to
