说明：  不适用matlab进行的bp算法开发,设计简单，功能健全(bp not using matlab)

This is the Newton Raphson program for power system

数字信号处理：基于BT法和周期图法估计信号功率谱(Digital signal processing: signal power spectrum is estimated based on the the BT Act and the periodogram)

绘制单架飞机（单目标）的时延多普勒关系图(Plot Delay-Doppler of single target.)

卡尔曼滤波器是一个对动态系统的状态序列进行线性最小误差估计的算法，一般用于线性系统。一般在运动跟踪领域中摄像机相对于目标物体运动有时属于非线性系统，但由于在一般运动跟踪问题中图像采集时间间隔较短，可近似将单位时间内目标在图像中的运动看作匀速运动，采用卡尔曼滤波器可以实现对目标运动参数的估计。(Kalman filter is a state sequence of linear dynamic systems smallest error estimation algorithm for linear systems in general. Usually in the field of motion tracking camera motion with respect to the target object may belong to nonlinear systems, but in general due to motion tracking problems shorter image acquisition time interval, a unit of time can be approximated to the target motion in the image is regarded as uniform motion, Kalman filter can achieve the target motion parameter estimation.)

该程序是自己编写的，是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的，其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行，并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)

matlab的pde工具箱很薄弱，同时只能处理有限复杂度的问题，利用comsol强大的有限元分析与多物理场的耦合性，解决相当完美。 matlab与多物理场有限元软件的结合，本程序需要安装matlab7.0以上以及comsol multiphysics 3.0以上版本，建立客户端后可以方便的利用matlab控制有限元软件，进行建模计算。 本程序描述的是点电荷周围的电场以及电势。适合于初学者(The pde matlab toolbox is very weak, and can only handle a limited complexity of the problem, by using comsol powerful finite element analysis and multi-physical field coupling to solve quite perfect. matlab and multi-physics finite element software combination, the above procedure to install matlab7.0 and comsol multiphysics 3.0 or later, after establishing the client can easily control the use of matlab finite element software to model calculations. This procedure describes the electric field around a point charge and the electric potential. Suitable for beginners)

这是一份MATLAB基础课件，由于我也是初学者，这部课件讲的很浅显，但比较适合初学者对MATLAB所有功能的一个初步了解内容包括涵数值数组及其运算， M文件和面向对象编成， 字符串数组， 符号变量， matlab 绘图 及 Simulnk动态仿真。以及两个基本浅显的程序题。此为第 1章。(This is a basic MATLAB courseware, because I am also a beginner, this software is very simple-speaking, but more suitable for beginners of all the features of MATLAB, a preliminary understanding of the content including the Han and its numerical array computing, M documents and for object into string array, variable symbols, matlab graphics and dynamic simulation Simulnk. As well as the two basic procedures for simple questions. This is Chapter 1.)

基于LDA的人脸识别软件，malab环境。很不错。(LDA-based face recognition software, malab environment. Is pretty good.)

fp=2400hz,fs=5000hz,rp=3db,rs=25db.求其3dB时的各项参数！(fp = 2400hz, fs = 5000hz, rp = 3db, rs = 25db. for its 3dB at the time of the parameters!)
