Function

vDSP_fft5_zopD

Computes an out-of-place radix-5 complex Fourier transform, either forward or inverse. The number of input and output values processed equals 5 times the power of 2 specified by parameter Log2N; double precision.

Declaration

void vDSP_fft5_zopD(FFTSetupD __Setup, const DSPDoubleSplitComplex *__A, vDSP_Stride __IA, const DSPDoubleSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __Log2N, FFTDirection __Direction);

Discussion

This is the same as vDSP_fft5_zop, except for the types of the Setup object and the A and C vectors.
