自己写的检测音频峰值包络的程序，需要的可以看一下(Write your own audio peak envelope detection process, the need to look at)

2D四杆桁架结构的MATLAB有限元分析实例 用于编程实现有限元计算(MATLAB finite element analysis example of 2D four truss structure)

附件是多元回归的参数检验的matlab程序。(the file is the matlab program of parameter test)

本程序峭度的计算程序，已做成工具包，可以直接调用(The program kurtosis calculation program, has made kit, you can call)

说明：  非线性方程组的牛顿迭代方法与非线性方程解法类似，也是求解非线性方程组的常用方法。(Nonlinear equations of the Newton iteration method and nonlinear equations similar to solving nonlinear equations is a common method.)

doa估计经典music 算法 构造简单入射信号,利用7天线阵接收信号,进行波达方向估计.(doa estimated classical music used to construct simple incident signals, using seven antenna reception of signals for DOA estimated.)

利用matlab实现的BP神经网络算法，对初学者很有用(matlab neural network to achieve the BP algorithm)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)
