基于扰动观察法的mppt算法，用m函数编写，光伏板接boost电路(The mppt algorithm based on the disturbance observation method is written by the m function, and the photovoltaic board is connected to the boost circuit.)

把数据从text文件中分离并生成矩阵，同时显示text中的文字(Data from text files and generates separate matrix, while the text display text)

利用matlab实现光纤的模式分布图的模拟。(Using matlab to achieve mode fiber distribution simulations.)

该算法是实现交叉分析表分析。包含卡方检验，似然比检验，交叉分析表，方向度量，对称度量。(The algorithm is to achieve cross-analysis table analysis. Contains the chi-square test, likelihood ratio test, cross analysis table, measure direction, symmetric metric.)

一般情况下，我们都是在MATLAB命令行或DOS命令行下编译MEX程序。 所用的命令就是：mex filename.c 这有很多不方便的地方： a. 虽然mex也可以编译C++的mex程序，但是它的主框架仍是C的 a. 当程序有多个模块时，需要多次使用mex命令，操作很麻烦 b. 不能利用VC特有的ClassWizard自动创建和维护类 c. 不能用MFC类库编写应用程序 d. 不能方便地进行类似VC的项目管理 本文详细解说如何在IDE中编译MEX程序(Under normal circumstances, we are all in the MATLAB command line or DOS command line program to compile MEX. Command is used by: mex filename.c This has a lot of inconvenient places: a. Although the mex can also compile C++ The mex program, but it is still the main frame C of a. When the procedure has a number of modules the need to repeatedly use the mex command, the operation is cumbersome b. Can not use VC-specific ClassWizard automatically create and maintain the category c. can not use MFC class library to write applications easily d. should not conduct a similar project management VC a detailed explanation of how this article IDE compiling MEX procedures)
