WebAug 31, 2024 · 1 I am new to FFTW library. I have successfully implemented 1D and 2D fft using FFTW library. I converted my 2D fft code into multithreaded 2D fft. But the results were completely opposite. Multithreaded 2D FFT code is taking longer time to run than serialized 2D FFT code. I am missing something somewhere. WebTo specify your installation of the FFTW library, write an FFT callback class. Share the callback class with others who want to use this FFTW library for FFTW calls in standalone code. The callback class must derive from the abstract class coder.fftw.StandaloneFFTW3Interface. Use this example callback class as a template.
