Matlab for the Bartlett Window:
In matlab, a length
Bartlett window is designed by the statement
w = bartlett(M);This is equivalent, for odd
![$ M$](http://www.dsprelated.com/josimages_new/sasp2/img26.png)
w = 2*(0:(M-1)/2)/(M-1); w = [w w((M-1)/2:-1:1)]';Note that, in contrast to the hanning function, but like the hann function, bartlett explicitly includes zeros at its endpoints:
>> bartlett(3) ans = 0 1 0The triang function in Matlab implements the triangular window corresponding to the hanning case:
>> triang(3) ans = 0.5000 1.0000 0.5000
