This MATLAB function returns an L-point symmetric Hann window in the column vector w. Most references to the Hanning window come from the signal processing literature, where it is used as one of many windowing functions for smoothing values. The Hanning window, after its inventor whose name was Von Hann, has the shape of one cycle of a cosine wave with added to it so it is always positive. Just as a side note: This version of the Hamming window has a .
The HANNING function is used to create a “window” for Fourier Transform filtering. It can be used to create both Hanning and Hamming windows. HannWindow represents a Hann window function of x. HannWindow] uses the parameter \. This perturbation serves to avoid using zero samples in the window itself.
Why bother to multiply explicitly by zero?
