Function

vDSP_fft_zriptD

Computes an in-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_zriptD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, const DSPDoubleSplitComplex *__Buffer, vDSP_Length __Log2N, FFTDirection __Direction);

Discussion

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

See also functions vDSP_create_fftsetupD and vDSP_destroy_fftsetupD.
