Function

vDSP_fft2d_ziptD(_:_:_:_:_:_:_:_:)

Computes an in-place double-precision complex discrete FFT, either from the spatial domain to the frequency domain (forward) or from the frequency domain to the spatial domain (inverse). A buffer is used for intermediate results.

Declaration

func vDSP_fft2d_ziptD(_ __Setup: FFTSetupD, _ __C: UnsafePointer<DSPDoubleSplitComplex>, _ __IC0: vDSP_Stride, _ __IC1: vDSP_Stride, _ __Buffer: UnsafePointer<DSPDoubleSplitComplex>, _ __Log2N0: vDSP_Length, _ __Log2N1: vDSP_Length, _ __Direction: FFTDirection)

Discussion

This function is the same as vDSP_fft2d_zipt(_:_:_:_:_:_:_:_:), except for the types of vectors Setup, C and Buffer.

See also functions vDSP_create_fftsetupD(_:_:) and vDSP_destroy_fftsetupD(_:).
