关于matlab的两篇很有用的文章，学习matlab的必备啊！(on Matlab two very useful article, the essential learning Matlab ah!)

说明：  基于matlab的调Q光纤激光器输出模拟(Output simulation of Q-switched fiber laser based on MATLAB)

我国配电网一般采用中性点非有效接地方式，该配电网通常被称为小电流接地系统。故障选线是长期以来国内外关注的一大难题。提供了一种判别单相接地故障的程序，以及程序所用的数据。数据是EMTP仿真结果。(China' s distribution network is generally used non-effectively grounded neutral manner, often referred to as the distribution Netcom small current grounding system. Fault line is a major concern of long-standing problem at home and abroad. Provides a ground fault identification procedures and procedures used by the data. EMTP simulation results data.)

C语言与MATLAB接口编程实例，主要是一些C语言与MATLAB 接口的程序，希望对大家有用(C language MATLAB interface programming examples, some of the C language and MATLAB interface program, and hope to be useful)

利用GramCharlier级数绘制累积概率分布图，具有较高精确度，推荐使用。(The use of Gram Charlier series draw cumulative probability distribution, with high accuracy, it is recommended to use.)

无线信号发送主要采用多位数据格式，编码可达上百万个不同重复(Wireless signal mainly adopts several data format, coding can be up to millions of different repetition)

采用matlab语言编写的用内点法罚函数解决问题的方法。(The MATLAB language is used to solve the problem by using the penalty function of the interior point method.)

xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。 仿真框架为： 1.标记信号和双音信号续接作为发送信号； 2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号； 3.用一个检测信号对收发信号进行相关运算； 4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点； 5. 输入0相位点位置，计算相对相位差。(xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.)

This file include matlab files to simulate example in "Basics of MATLAB and Beyond - Andrew Knight" e-book, you can use these .m file to improve your knowledge about matlab
