运用dde23求解时滞微分方程的，时程曲线和分岔程序。(Solve the delay differention equation using dde23.)

In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero-valued outside of some chosen interval. For instance, a function that is constant inside the interval and zero elsewhere is called a rectangular window, which describes the shape of its graphical representation. When another function or waveform/data-sequence is multiplied by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap, the view through the window .

非线性方程的Matlab程序，主要用于代入非线性方程的数学问题(Matlab program of nonlinear equations, mainly for generation of nonlinear equations into mathematical problems)

（1） 使用录音软件或者Matlab函数，分别采集一段浊音和清音语音信号（是你自己说的，如：a，o，s等），采样率为8KHz，量化精度为16比特线性码，存在自己指定的目录下，例如D盘根目录下叫sound的文件夹中，录音文件名为yourfilename_a.wav，yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。 （2） 根据语音信号的短时平稳特性，分析帧长取30ms（或10ms～50ms）； （3） 利用上述基音提取的三种方法（任选两种方法）的编程流程图（图1、图2和图3）编制浊音语音基音提取的matlab程序，上机调试给出相应波形，并根据图形，分析计算出基音周期。所用公式为： (1.5) 其中 是基音脉冲处所对应的位置， 是抽样频率， 是基音周期。 （4） 将语音信号换为清音语音，运行程序，与浊音语音的运行结果进行比较，并得出结论。 ( voice signal processing)

基于MATLAB和电子表格共同的有限元程序。电子表格进行前处理，MATLAB读入进行计算及后处理。(Based on MATLAB and Spreadsheets a common finite element program. Before dealing with spreadsheets, MATLAB reads the calculation and post-processing.)
