tftb_window.m 短时傅立叶变换窗函数，在进行短时傅立叶变换时使用tfrstft函数，其中h-窗函数调整时使用的函数。
tftb_window Window generation.
H=tftb_window(N,NAME,PARAM,PARAM2)
yields a window of length N with a given shape.
N : length of the window
NAME : name of the window shape (default : Hamming)
PARAM : optional parameter
PARAM2 : second optional parameters
Possible names are :
"Hamming", "Hanning", "Nuttall", "Papoulis", "Harris",
"Rect", "Triang", "Bartlett", "BartHann", "Blackman"
"Gauss", "Parzen", "Kaiser", "Dolph", "Hanna".
"Nutbess", "spline", "Flattop"
For the gaussian window, an optionnal parameter K
sets the value at both extremities. The default value is 0.005
