Function

vDSP_fftm_zoptD(_:_:_:_:_:_:_:_:_:_:_:)

Performs the same operation as vDSP_fft_zoptD(_:_:_:_:_:_:_:_:), but on multiple signals with a single call.

Declaration

func vDSP_fftm_zoptD(_ __Setup: FFTSetupD, _ __A: UnsafePointer<DSPDoubleSplitComplex>, _ __IA: vDSP_Stride, _ __IMA: vDSP_Stride, _ __C: UnsafePointer<DSPDoubleSplitComplex>, _ __IC: vDSP_Stride, _ __IMC: vDSP_Stride, _ __Buffer: UnsafePointer<DSPDoubleSplitComplex>, _ __Log2N: vDSP_Length, _ __M: vDSP_Length, _ __Direction: FFTDirection)

Discussion

This is the same as vDSP_fftm_zopt(_:_:_:_:_:_:_:_:_:_:_:), except for the types of the Setup object and the A, C, and Buffer vectors.

See also functions vDSP_create_fftsetupD(_:_:), vDSP_destroy_fftsetupD(_:), and vDSP Programming Guide.
