介绍MATLAB的一些常用指令，有利于我们更好更快熟悉使用MATLAB(show some orders to us about matlab,you will get some chivement )

说明：  冈萨雷斯《数字图像处理（matlab)》书中的图片集（简称老冈书的图片）(The pictures used in the book of Digital Image Processing Using MATLAB,written by Gonzalez)

使用matlab编写的 配电网前推回代潮流计算程序 使用IEEE 33节点配电系统作为算例，可实现弱环网情况下的潮流计算(Matlab prepared using forward and backward substitution distribution network power flow calculation program uses IEEE 33 node power distribution system as an example, can be realized in case of weak-link network flow calculation)

该程序的作用用于产生正交多项式.该压缩包内含有多个M文件,其中Approximation.m文件为主要的函数文件,它会调用其他的函数文件.该函数提供了和Matlab自身提供的函数一样的条用方式.(The role of the program used to generate orthogonal polynomials. The package contains a number of M documents, including documents Approximation.m function as the main document, it will call a function of other documents. The Matlab function provided and provide their own be a function with the same way.)

四种高斯滤波算法的比较：EKF、UKF、QKF和CKF(Comparison of four Gaussian filtering algorithm: EKF, UKF, QKF and CKF)

基于小波分析的故障检测方法，在容错组合导航方面应用，很不错的资料(Fault detection method based on wavelet analysis, the application of fault-tolerant integrated navigation, very good information)

模型是非机动模型的卡尔曼滤波的程序及其应用(Model of non-motorized model of Kalman filter process and its application)

说明：  MATLAB中画椭圆的自定义函数：ellipse，用后才会发现这个函数的强大功能！ 在ellipse之函数当中，其输入之变数分别如下： -ra 椭圆之长轴半径，可为列矩阵，若为列矩阵时，代表可同时绘制许多椭圆。 -rb 椭圆之矩轴半径，可为列矩阵，如ra。 -ang 水平轴之倾斜角，以弧度表示。可为列矩阵，但ra、rb、ang三者之矩阵数应相同。 -x0,y0 圆心之座标，可为矩阵，若为矩阵时，代表可同时绘制许多不同圆心位置之椭圆。 -C 椭圆线之颜色 -Nb 绘椭圆时所用之点数。(MATLAB in the oval painting custom function: ellipse, will be found after using the power of this function! Ellipse of the function in which its input variables are as follows:-ra ellipse of major axis radius for the column matrix, if for the column matrix, a representative may at the same time drawing many elliptical. oval-rb-axis radius of the moment for column matrices, such as ra.-ang horizontal axis of the tilt angle to radians. Matrix for the column, but ra, rb, ang among several of the matrix should be the same.-x0, y0 the coordinates of the center for the matrix, if for the matrix, a representative may at the same time drawing a number of different oval center location.-C elliptic line color-Nb painted oval of points used.)

说明：  matlab数值编程使得数值计算工作量大大减轻，但是由于它其实是一种解释语言，而且没有国际标准，另外也没法在没有安装matlab的计算机上运行，不能用于计算密集型应用场合，极大地限制了它地应用，主要应用于物理，数学和化学，部分工程应用领域的计算工作量小的科技工作者。计算工作量大的工作，如流体力学求解，虽然matlab有解偏微分方程组的方法，但那几乎是用来作为例子来说明的，换句话说，只能作为上课例子。大型流体力学计算是计算密集型的一个例子，需要高效运算程序或并行化处理。 (chao liu ji suan)

预测控制的两个实例，用M语言编写，希望对学习预测控制的人有多帮助(Two examples of predictive control, the M language, in the hope that people learn how predictive control to help sponser links)
