Copy
public void CyclicCorrelation(
	double[] src1real,
	double[] src1imag,
	double[] src2real,
	double[] src2imag,
	double[] resultreal,
	double[] resultimag,
	int n
)

Parameters

src1real  Double
The real part of the first input array (will be destroyed).
src1imag  Double
The imaginary part of the first input array (will be destroyed).
src2real  Double
The real part of the second input array (will be destroyed).
src2imag  Double
The imaginary part of the second input array (will be destroyed).
resultreal  Double
The real part of the result. (may be identical with arr1 or arr2).
resultimag  Double
The imaginary part of the result (may be identical with arr1 or arr2).
n  Int32
The length of the convolution. Has to be equal or smaller than the array size. Has to be a power of 2!
Remarks
Two helper arrays of length n are automatially allocated and freed during the operation.
