说明：  利用matlab工具箱函数，分别画出长度为15的矩形窗、汉宁窗、汉明窗和布莱克曼窗的幅频（dB）特性曲线，观察它们的主要参数（主瓣宽度、过渡带宽度、旁瓣峰值幅度）的差别。(Matlab toolbox function is used to draw the amplit-frequency (dB) characteristic curves of rectangular window, hanning window, hamming window and blackman window with the length of 15, and observe the difference of their main parameters (main lobe width, transition band width, side lobe peak amplitude).)

这是一篇关于博士论文，论文上详细的讲了非线性时间序列分析：辨识、预测与控制，很有用哦！(This is an article on the doctoral dissertation, the paper stresses on the detailed analysis of nonlinear time series: identification, prediction and control, useful Oh!)
