WebDec 22, 2024 · To create the plans, declare two fftw_plan variables as globals (two plans: one for forward, another for backwards) and use fftw_plan_dft_1d to initialize each of them. Then at the end of main, call fftw_destroy_plan on each of them to clean up. After several tried, here is the successful FFTW hilbert () improvement.
