实现music根算法仿真，使用matlab仿真环境。可成功运行(generate an root-music simulation program)

This code is related to the course Digital Communications. It reproduce the error probability as a function of the SNR per bit for 16-QAM. Enjoy it!

Pan-Tompkins algorithm in Matlab for ECG signal analysis.

％电影动画： ％1.首先调用moviein函数对内存初始化.创建一个足够大的矩阵来容纳一系列指定的图形（帧） ％2.调用getframe函数生成每一帧.该函数返回一个矢量，利用这个矢量创建一个电影动画矩阵 ％3.调用movie函数按照指定速度进行指定次数的播放 ％例子2：演示如何实现快速傅立叶变换（exp(j*2*pi/n)）的可视化过程( Movie animation: 1. First transfers the moviein function to the memory initialization Founds graph which an enough big matrix holds a series of assigns (frame) % 2. Transfers the getframe function to produce each This function returns to a vector, uses this vector to found a movie animation matrix % 3. Transfers the movie function according to assign the speed to carry on assigns the number of times the broadcast Example 2: How demonstrates realizes fast Fourier transforms (exp (j*2*pi/n)) the visible process )

产生白噪声，并对白噪声进行fft，画出白噪声的频谱。(White noise and white noise fft, draw a white noise spectrum.)

基于Prony算法的电力系统低频振荡分析工具箱，美国学者开发，非常实用(Based on Power System Low Frequency Oscillation analysis toolbox Prony algorithm, an American scholar development, very practical)

频率估计 1）产生一个单频实信号，加上一定信噪比的噪声。 2）对含噪声的信号进行频率估计。估计方法可以查阅相关文献。 3）统计估计出来的频率和真实频率之间的误差。 4）验证该频率估计算法在不同信噪比、不同数据长度下、不同频率时候的性能。 (Frequency estimation 1) produce a single-frequency real signal, plus a certain SNR noise. 2) noisy signal frequency estimates. Estimation method can access relevant literature. 3) out of the statistical estimation and frequency error between the true frequency. 4) Verify that the frequency estimation algorithm under different SNR, different data length, when the frequency of different properties.)

此程序用于对时间序列数据做协整性检验以及granger因果检验(This program is used to cointegration tests and Granger tests)

控制表的程序实现，用语言编写存入文本文档中(Program control table, use the language into the text document)

此为层次分析法的MATLAB源程序，并有详细说明(This is the AHP MATLAB source, and a detailed description of)
