Using the Code Replacement Library (CRL), you can generate optimized Simulation software uses the library that MATLAB uses for FFT algorithms. To compute an -point DFT when is composite (that is, when ), the FFTW library decomposes the problem using the Cooley-Tukey algorithm 1, which first computes transforms of size, and then computes transforms of size. Information about an FFT library callback class, see 3Interface (MATLAB Coder).įor simulation of a MATLAB Function block, the The FFT functions (fft, fft2, fftn, ifft, ifft2, ifftn) are based on a library called FFTW. To generate calls to a specific installedįFTW library, provide an FFT library callback class. For standalone C/C++ code, byĭefault, the code generator produces code for FFT algorithms instead of For limitations related to variable-size data, see Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder).Ĭoder™ uses the library that MATLAB uses for FFT algorithms.
