# vDSP_DFT_Interleaved_SetupD

An opaque type that contains setup information for an interleaved double-precision discrete Fourier transform (DFT).

## Declaration

```swift
typealias vDSP_DFT_Interleaved_SetupD = OpaquePointer
```

## Discussion

Discussion Call the vDSP_DFT_Interleaved_CreateSetupD(_:_:_:_:) function to initialize and allocate a new setup object. Call vDSP_DFT_Interleaved_DestroySetupD(_:) to free the resources associated with a setup object.
