[Discuss-gnuradio] Pathological FFT sizes

2009-03-09 Thread Marcus D. Leech
I discovered, rather by accident, that the FFTW planner seems to get its knickers royally in a twist for certain FFT sizes. The code d_plan = fftwf_plan_dft_1d (fft_size, reinterpret_cast(d_inbuf), reinterpret_cast(d_outbuf),
