# vDSP_DFT_SetupD

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

## Declaration

```swift
typealias vDSP_DFT_SetupD = OpaquePointer
```

## Discussion

Discussion Call the vDSP_DFT_zop_CreateSetupD and vDSP_DFT_zrop_CreateSetupD functions to initialize and allocate a new setup object. Call vDSP_DFT_DestroySetup to free the resources associated with a setup object.
