Design two Hamming windows: The first window has N = 64 and is symmetric. The second window has N = 63 and is periodic. Display the two windows. Hs = hamming (64, 'symmetric'); Hp = hamming (63, 'periodic'); wvt = wvtool (Hs,Hp); legend (wvt.CurrentAxes, 'Symmetric', 'Periodic')

Add a new window — Adds a default Hamming window with length 64 and symmetric sampling. You can change the information for this window by applying changes made in the Current Window Information panel.
As far as I understand both the time series' length and window function length(hamming or hanning) should be same. But for smoothing the fourier amplitude spectrum, optimum window length can vary. How this procedure should be apply in matlab?
w = window(fhandle,n,winopt) returns the window specified by its function handle, fhandle, and its winopt value or sampling descriptor. For chebwin , kaiser , and tukeywin , you must enter a winopt value.
The following model uses the Window Function block to generate and apply a Hamming window to a 3-dimensional input array. In this example, set the Operation parameter of the Window Function block to Generate and apply window.
20 lis 2012 · When generating windows in Matlab, you can add the 'periodic' option. Then, if you have a 50% overlap, two conseccutive windows will have their overlap equal to one. As an example you can try: w=hanning(100,'periodic'); x=w(1:50)+w(51:100); unique(x) ans = 1.0000
This MATLAB function returns an L-point symmetric Hamming window.
