Syntax

public static void FFT(
	double[] x,
	double[] y,
	uint n,
	FourierDirection direction,
	ref Object?? temporaryStorage
)

x Double: Array of real values.
y Double: Array of imaginary values.
n UInt32: Number of points to transform.
direction FourierDirection: Direction of Fourier transform.
temporaryStorage Object: On return, this reference holds an object for temporary storage. You can use this in subsequent FFTs of the same size.
