The Discrete Fourier transformation (DFT) for given two frequencies.

Syntax
C#
Visual Basic
public static void GoertzTwo([In] TVec Src, double Freq0, double Freq1, ref TCplx Result0, ref TCplx Result1);
Remarks

Calculates the Discrete Fourier transformation (DFT) for two given frequencies. Goertz returns the DFT at the two frequencies pass as a parameter. Each value of the DFT computed by the Goertzel algorithm takes 2N+2 real multiplications and 4N real additions. FFT computes the DFT with N*log2(N) of real multiplications and additions.
