# transform(inputReal:inputImaginary:outputReal:outputImaginary:)

Computes a double-precision discrete Fourier transform.

```
func transform<U, V>(inputReal: U, inputImaginary: U, outputReal: inout V, outputImaginary: inout V) where U : AccelerateBuffer, V : AccelerateMutableBuffer, U.Element == Double, V.Element == Double
```

## Parameters

`inputReal`

An array that contains the real parts of the input.

`inputImaginary`

An array that contains the imaginary parts of the input.

`outputReal`

An array that contains the real parts of the output.

`outputImaginary`

An array that contains the imaginary parts of the output.
