static · iOS 13.0+ · Deprecated makeDFTSetup TypeScript static makeDFTSetup(previous: (vDSP_DFT<number>) | null, count: number, direction: vDSP_FourierTransformDirection, transformType: vDSP_DFTTransformType): (SDKHandle) | nullSwift declaration static func makeDFTSetup<T>(previous: vDSP.DFT<T>? = nil, count: Int, direction: vDSP.FourierTransformDirection, transformType: vDSP.DFTTransformType) -> OpaquePointer? where T : vDSP_FloatingPointDiscreteFourierTransformableReturns a data structure for use with to perform a discrete Fourier transform
- Parameter previous: a previous vDSP_DFT instance to share data with.
- Parameter count: the number of real elements to be transformed.
- Parameter direction: Specifies the transform direction.
- Parameter transformType: Specficies whether to forward transform is real-to-complex or complex-to-complex.

static · iOS 13.0+ · Deprecated transform TypeScript static transform(dftSetup: SDKHandle, inputReal: Array<number>, inputImaginary: Array<number>, outputReal: Array<number>, outputImaginary: Array<number>): { $ret: null; $out: { "outputReal": Array<number>; "outputImaginary": Array<number> } }Swift declaration static func transform<U, V>(dftSetup: OpaquePointer, inputReal: U, inputImaginary: U, outputReal: inout V, outputImaginary: inout V) where U : AccelerateBuffer, V : AccelerateMutableBuffer, U.Element == Double, V.Element == DoubleComputes an out-of-place single-precision real discrete Fourier transform.
- Parameter dftSetup: A DCT setup object.
- Parameter inputReal: Input vector - real part.
- Parameter inputImaginary: Input vector - imaginary part.
- Parameter outputReal: Output vector - real part.
- Parameter outputImaginary: Output vector - imaginary part.
Omit the output parameters from the call. The result contains $ret and $out, with outputReal, outputImaginary inside $out.
