伽博同轴全息记录与再现。通过衍射计算完成光学同轴全息记录与再现过程的仿真，可以观察再现像的特点。(Bo coaxial holographic recording and playback.Completed through the calculation of the diffraction optical coaxial holographic recording and playback process simulation, can observe reproduce like characteristics.)

说明：  通过修改inp文件，用于对abaqus的模型进行自动创建裂纹的程序(by modifying inp. file, used for create a crack in abaqus model)

该程序是基于Matlab编写的模拟退火工具软件包，可以很方便地用于其他领域的优化计算。(The program is based on the Matlab tool for the preparation of the simulated annealing package, can be easily used in other areas of the optimization calculation.)

最小生成树源代码，给定一个邻接矩阵，可以画出一个最小生成树的图(The minimum spanning tree of source code, given an adjacency matrix, can draw a minimum spanning tree of a graph )

这是一个matlab主程序，介绍的是几种混沌系统吸引子的图像的主程序(This is a matlab main program, introduced several chaotic attractor is an image of the main program)

一个用MFC写的滤波器源代码，代码结构非常精巧，可以参考 功能：1 固定带通滤波 2 可变带通滤波 3 噪声删除 4 输入输出误差计算 实现比较简单，由于使用了Microsoft Foundation classes，代码流程很简单，但是实现的功能比较充分 Filter.h：头文件，定义了CFilterApp 类 Filter.cpp：利用MFC的函数实现了CFilterApp Filter.rc：资源文件，包括对话框和图标的说明(use a filter to write MFC source code, code structure is very delicate, can be functional : a fixed band-pass filtering two variable bandpass filter to delete four 3 noise input and output error calculation is relatively simple to achieve. As the use of Microsoft Foundation classes, code process is simple, but to achieve the more fully functional Filter.h : The first document, CFilterApp definition of the category Filter.cpp : MFC function realized CFilterApp Filter.rc : resource files, including dialog box and the note icon)

包含Jacobi和Seidel两种迭代法，用于求解线性方程，计算简单，收敛快(Contains two kinds of Jacobi and Seidel iterative method for solving linear equations, computing simple, fast convergence)

说明：  随机森林算法程序，用于对数据的仿真预测，是一个有用的算法(Random forest algorithm program)
