The Discrete Fourier transformation (DFT) for vector of frequencies.

Syntax
C#
Visual Basic
public static void Goertz([In] TVec Src, [In] TVec Freq, [In] TVec Dst);
Remarks

Calculates the Discrete Fourier transformation (DFT) for an array of frequencies defined in the Freq parameter. Goertz returns the DFT of the frequencies pass as a parameter in the Dst variable. 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.
