Blackman-Harris window.

Syntax
C#
Visual Basic
public static TVec BlackmanHarris([In] TVec Src, TSignalWindowMode WindowMode);
Remarks

Applies BlackmanHarris window to Src. Window functions are applied to the signal prior to conversion to frequency domain with the FFT algorithm, to reduce the spectral leakage. Their side-effect is a lower frequency resolution. 

w[n] := 0.42323 - 0.49755*cos(2*Pi*n/(n-1)) + 0.07922*cos(4*Pi*n/(n-1)) 

0 <= n <= M - 1
