WebJun 11, 2024 · I'm testing the FFTW 3.3.8 C library for 1D Discrete Fourier Transform (DFT) calculations. The results I get are often incorrect when I use the float (single-precision) version of the libraries, configured with the --enable-generic-simd128 or --enable-generic-simd256 options (and --enable-float for float support). I have tested this in MinGW-w64 … Webvoid fftwf_execute(const fftw_plan plan); void fftwf_destroy_plan(const fftw_plan plan); 2. Basic Interface Wrappers. Wrappers for execution and plan destruction functions are listed in Wrappers for Using Plans. 2.1 Complex DFTs. fftw_plan fftw_plan_dft_1d(int n, fftw_complex *in, fftw_complex *out, int sign, unsigned flags);
