Web6 jun. 2024 · In Matlab, hanning (n) creates a symmetric window. From the code in file hanning.m, for even n the first half of this window is computed as m = n/2; w = .5* (1 - cos (2*pi* (1:m).'/ (n+1))) and then the full window is obtained as w = [w; w (end:-1:1)]. WebThe Hanning window is a taper formed by using a weighted cosine. Parameters: Mint Number of points in the output window. If zero or less, an empty array is returned. Returns: outndarray, shape (M,) The window, with the maximum value normalized to one (the value one appears only if M is odd). See also bartlett, blackman, hamming, kaiser Notes
