transform(real:imaginary:)
Returns the result of a double-precision discrete Fourier transform.
Declaration
func transform<U>(real: U, imaginary: U) -> (real: [Double], imaginary: [Double]) where U : AccelerateBuffer, U.Element == DoubleParameters
- real:
An array that contains the real parts of the input.
- imaginary:
An array that contains the imaginary parts of the input.
Return Value
A tuple of two arrays that represents the real and imaginary parts of the output.
