FFTInverseReal(Complex, Int32) Method

Inverse real Fast Fourier Transform.

Namespace: Austra.Library.Transforms
Assembly: Austra.Library (in Austra.Library.dll) Version: 2.5.0+44e7797405725ef3cf24b3ff0eba94ce6c649601
Syntax
C#
Copy
public static double[] InverseReal(
	Complex[] f,
	int n
)

Parameters

f  Complex
Samples to be transformed.
n  Int32
The size of the problem.

Return Value

Double
The original samples.
Remarks
f should satisfy f[k] = f[n - k]', so just one half of frequencies array is needed.
f[0] is always real.
If n is even, f[n/2] is real too.
