Function

vDSP_fftm_zripD

Performs the same operation as vDSP_fft_zripD, but on multiple signals with a single call.

Declaration

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

Discussion

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