tftb_window.m 短时傅立叶变换窗函数

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
