Function

vDSP_fftm_zropD

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

Declaration

void vDSP_fftm_zropD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, vDSP_Stride __IMA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Stride __IMC, vDSP_Length __Log2N, vDSP_Length __M, FFTDirection __Direction);

Discussion

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