Wavelet-tutorial

用工具箱实现正弦函数的逼近，BP逼近与RBF的逼近

说明：  采用最小二乘法进行系统辨识，本例是一个简短的例程序。(System identification using the least square method, in this case is a short example program.)

程佩青版数字信号处理部分作业的matlab程序... 只做过了老师布置的题目. (Cheng Peiqing version of digital signal processing operations matlab program ... )

PID模糊小车直线控制，用MATLAB编写，运行后绘制小车运动轨迹(PID fuzzy car straight-line control, using MATLAB, and run after drawing the car trajectory)

在matlab环境下面编程，最好使用2012版本及其以上，完成利用matlab软件提供的图像处理函数来完成图像匹配，3D重建的工作。最后的效果图很好，由于是利用matlab自带的图片，所以压缩文件中无图片，直接打开m文件就可以运行！(Below programming in matlab environment, it is best to use 2012 version and above, using matlab software provides complete image processing function to complete the image matching, 3D reconstruction work. The final renderings good, as is the use of matlab comes with a picture, so the compressed file without pictures, you can directly open the m-file to run!)

Matlab工具箱 - 《复分析基础及工程应用 第3版》，这是书中所带工具箱，与Matlab本身的复分析工具箱相背相比，更适用于教学。(Matlab Toolbox- Fundamentals of Complex Analysis with Applications to Engineering and Science the 3rd version,compared with the similar toolbox of matlab,this toolbox is good at teaching.)

潮流计算是电力学名词，指在给定电力系统网络拓扑、元件参数和发电、负荷参量条件下，计算有功功率、无功功率及电压在电力网中的分布。潮流计算是根据给定的电网结构、参数和发电机、负荷等元件的运行条件，确定电力系统各部分稳态运行状态参数的计算。通常给定的运行条件有系统中各电源和负荷点的功率、枢纽点电压、平衡点的电压和相位角。待求的运行状态参量包括电网各母线节点的电压幅值和相角，以及各支路的功率分布、网络的功率损耗等。(Power flow calculation is a term of power science. It refers to the calculation of the distribution of active power, reactive power and voltage in power network under given network topology, component parameters and generation and load parameters. Power flow calculation is based on the given grid structure, parameters and operation conditions of generator, load and other components to determine the steady-state operation parameters of each part of the power system. Usually, the given operating conditions include the power of each power source and load point, junction voltage, balance point voltage and phase angle. The parameters to be determined include the voltage amplitude and phase angle of each bus node, the power distribution of each branch and the power loss of the network.)

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善(matlab scientific computing continue to upload a total of 10 chapters, easy-to-digest, almost, including most of the scientific method of calculation and simulation. I have done a part of algorithm optimization, a more perfect)
