实现控制仿真，利用亚当姆斯法，对于阶跃响应的数字仿真(realise control simulink)

利用matlab 做拟合的图表 两个序列进行拟合 并画出拟合后的图和残差 另外作图的过程是每次都取相同的一段数据 且起始点不断往后推(Using matlab to do a chart to fit the proposed merger of two sequences and residual process diagram plotting another draw after fitting is always take the same piece of data and constantly pushed back the starting point)

梁元进行有限元分析时可利用的函数，很不错，有一定价值(Beam element for finite element analysis of available functions, very good, there is some value)

是有关小波分析mallat算法，简便实用(Is related to wavelet analysis mallat algorithm, simple and practical)

active filter shunt so good simpower system simulation

说明：  文字识别一块的例程 包含字符分割 车牌识别 文字识别等内容(The routine of character recognition)

simulink的课件的PPT，适合入门者使用(the ppt of simulink and it is the base of simulink)

现有的代数特征的抽取方法绝大多数采用一维的方法，即首先将图像转换为一维向量，再用主分量分析（PCA）,Fisher线性鉴别分析（LDA）,Fisherfaces式核主分量分析（KPCA）等方法抽取特征，然后用适合的分类器分类。针对一维方法维数过高，计算量大，协方差矩阵常常是奇异矩阵等不足，提出了二维的图像特征抽取方法，计算量小，协方差矩阵一般是可逆的，且识别率较高。(existing algebra feature extraction method using a majority of the peacekeepers, First images will be converted into one-dimensional vector, and then principal component analysis (PCA), Fisher Linear Discriminant Analysis (LDA), Fisherfaces audits principal component analysis (KPCA), and other selected characteristics, then use the appropriate classification for classification. Victoria against an excessive dimension method, calculation, covariance matrix is often inadequate singular matrix, a two-dimensional image feature extraction method, a small amount of covariance matrix is usually reversible, and the recognition rate higher.)

不错的灰度处理matlab程序 实验过 有些地方需要修改更好(good handle Matlab experimental procedure that some places need to be amended to better)
