Function

vDSP_fft_zroptD

Computes an out-of-place double-precision real discrete Fourier transform, either from the time domain to the frequency domain (forward) or from the frequency domain to the time domain (inverse).

Declaration

void vDSP_fft_zroptD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, const DSPDoubleSplitComplex *__Buffer, vDSP_Length __Log2N, FFTDirection __Direction);

Discussion

This is the same as vDSP_fft_zropt, except for the types of the Setup object and the A, C, and Buffer vectors.

See also functions vDSP_create_fftsetupD and vDSP_destroy_fftsetupD.
