matlab算法第九章内容其他部分陆续上载中请稍后.(Chapter IX matlab algorithm for the rest be uploaded in a moment.)

1 swing bus、1 PQ bus、2 transfermor 以matlab劃出結構圖後計算各線路的電流電壓(1 swing bus, 1 PQ bus, 2 transfermor matlab draw diagram after calculation of current and voltage of each line)

用matlab写的一些数值算法，大家可以参看，很不错的 (using Matlab write some numerical algorithm, we can see very good)

使用sinulink中自带搭建的dq－αβ变换模块，可直接使用(Comes built in with sinulink dq-αβ transformation module can be used directly)

说明：  1. 编程实现图像傅立叶高通、低通滤波。 2. 尝试傅立叶压缩。 (1. Programming image Fourier high-pass, low pass filtering. 2. Try Fourier compression.)

一个关于量化噪声分析的程序。代码不长仅供参考。学生试验专用。(One of the quantization noise analysis program. The code is not long for reference only. Students of special test.)

用matlab写的经验模式分解程序。可作希尔伯特-黄变换，画时频图。(Empirical mode decomposition process Written by matlab .It Can be used for Hilbert- Huang Transform and time-frequency analysis.)

对序列建立AR模型，并以概率形式给出预测数列表达。先进行平稳性检验后求取自相关函数，用Y-W法求取模型参数，并应用FPE准则确定阶数，进行预测后，给出概率表达。(AR model for the sequence established, and the probability forecast given in the form of a list. After a smooth first autocorrelation function test strike strike model parameters YW law and apply the criteria to determine the order of FPE, predict, given the probability of expression.)

说明：  Expectation-Maximization algorithm

Code to simulate 2theta-omega scans for InGaN/GaN films
