Matlab鼠标画图,用pop-up menu选择画图标记,颜色edit记录鼠标坐标 但是功能比较简单，只能画线，不能画矩形、椭圆等 其中一个难点就是：拖动鼠标的过程中如何显示矩形/椭圆的轮廓，并且轮廓跟着鼠标指针移动。 程序的亮点： 1、可选择点、线、矩形、椭圆进行画图； 2、可选择marker、LineTyple进行画图； 3、可选择画图颜色； 4、可实时显示鼠标指针当前坐标； 5、可清除画板； 6、可保存画好的图(bmp、jpg、gif)； 7、操作比较人性化，模仿了windows画板； 8、该程序牵涉的面广，是一个很好的GUI学习资料。 (Matlab mouse drawing, with the pop-up menu select the drawing marks, color edit record mouse coordinates, but relatively simple function, can only draw a line, not drawing rectangles, ellipses, etc. One of the difficulties is this: how the process of dragging the rectangle/oval contours, and outline follow the mouse pointer moves. Program Highlights: 1, select point, line, rectangle, ellipse for drawing 2, optional marker, LineTyple the drawing 3, choose paint colors 4, real-time display the current coordinates of the mouse pointer 5, to clear the drawing board 6, save-drawn map (bmp, jpg, gif) 7, operation more user-friendly, imitating the windows drawing board 8, the program involved a wide range, the GUI is a good learning materials.)

形状分割，采用指标为短轴与长轴之比，骨架复杂度。效果很好，预处理合理(Shape segmentation, the use of indicators for the short axis and long axis ratio, frame complexity. Good effect, pre-rational)

这是关于matlab语言学习的经验，其中包括两个txt文档很方便下载，可以在手机上看，写的很好，值得看看。(This is about the matlab language learning experience, including two txt documents easy to download, you can phone point of view, well written, it is worth a look.)

二维正态分布的检验函数，如果需要进行二维正态分布的检验，在你的程序运行前运行此程序，就可直接调用函数功能。(Dimensional normal distribution test function, if you need a two-dimensional normal distribution test, run your program before you run this program, you can directly call the function function.)

数据库的完整性控制熟悉利用企业管理器为列创建DEFAULT约束、为列创建CHECK约束、为列创建UNIQUE约束、为列创建不允许为空约束、创建PRIMARY KEY约束、创建FOREIGN KEY约束(Integrity control of the database use Enterprise Manager to create the familiar column DEFAULT constraint, create a CHECK constraint for a column, create a UNIQUE constraint for a column, create a column does not allow null constraint, create a PRIMARY KEY constraint, create FOREIGN KEY constraint)

通过非线性扩张观测器可实现被控对象的位置、速度和未知部分观测。在实际控制工程中，可采用本观测器实现无需速度测量的控制，并实现对未知不确定性和外加干扰补偿(Through the expansion of nonlinear observer can realize the location of the controlled object, speed and unknown part of the observation. Can be used in actual control engineering, the observer is to realize the control without speed measurement, and implement the unknown uncertainties and external disturbance compensation)

说明：  首先从微电源、储能元件、负荷各方面对微网建模展开研究,并在对现有的电力系统随机潮流算法进行全面对比分析的基础上,重点研究了基于半不变量及Gram-Charlier级数的随机潮流算法,将其应用于微网的随机潮流计算分析中。(Firstly, micro-grid modeling is studied from the aspects of micro-power supply, energy storage components and load. On the basis of comprehensive comparative analysis of existing power system stochastic power flow algorithms, the stochastic power flow algorithm based on semi-invariant and Gram-Charlier series is studied, and applied to the stochastic power flow calculation and analysis of micro-grid.)

说明：  地形数据显示matlab文件包 这是外国人编写的一个工具程序包(Terrain data matlab package This is a tool for foreigners to prepare package)
