A Dynamical Tikhonov Regularization for Solving Ill-posed Linear Algebraic Systems.pdf，以上论文提出的求解病态线性方程组的一种较新梯度下降法(A Dynamical Tikhonov Regularization for Solving Ill-posed Linear Algebraic Systems.pdf, more than one paper proposes solving ill-conditioned linear equations newer gradient descent)

分析一个文件夹及其子文件夹下所有的html文档，并查找文档中加载的png图片文件，通过urlwrite函数下载并保存png类型的图片文件到硬盘上。 此matlab代码用到了网络连接，下载，并且通过多线程技术，增加了下载的速度。 可以通过这个方法，下载网页中的内容，可以说想怎么下，就怎么下。(Analysis all the files of type html in a folder, find the documents that load png image file.Then download and save the png file to harddisk through urlwrite function .)

卡曼滤波的实例程序，用来实现卡曼滤波，是自己结合实例亲自编的(Kalman filtering of the example program, used to implement Kalman filtering, with examples their own personal series of)

说明：  推箱子游戏,这是用matlab语言编写的源程序，有意思。(Sokoban game, which is used matlab source languages, interesting.)

说明：  matlab dct－lms自适应算法仿真例子，该例子做了dct－lms和lms的比较。(Matlab Extra-LMS adaptive algorithm simulation example, the example done Extra-LMS and LMS comparison.)

carlight1中是一个用C编的程序，用于计算每条光线在测试屏上的坐标(carlight 1 is a C series of the program, each ray is used to calculate the coordinates on the screen in the test)

极大似然估计法用于系统模型辨识，需要构造一个以观测数据和未知参数为自变量的似然函数。(Maximum likelihood estimation method for system model identification, the need to construct a likelihood function as independent variables to the observed data and the unknown parameters.)

首先通过自相关 偏自相关分析获得特征向量的维数，随后继续运行后面的代码以获得预测值,该方法为最近邻抽样回归预测(The dimension of feature vectors will be obtained by the autocorrelation and partial autocorrelation analysis, then continue to run the code behind to get predicted value，its short name is NNBR)
