Function

vDSP_fft_zipD

Computes an in-place double-precision complex discrete Fourier transform of the input/output vector signal, either from the time domain to the frequency domain (forward) or from the frequency domain to the time domain (inverse). Does not use temporary memory.

Declaration

void vDSP_fft_zipD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __Log2N, FFTDirection __Direction);

Discussion

This is the same as vDSP_fft_zip, except for the types of the Setup object and the C vector.

See also functions vDSP_create_fftsetupD and vDSP_destroy_fftsetupD.
