说明：  主成分分析算法，有大量数据，初学者可以根据数据看程序，并且可以出现图像(Principal component analysis algorithm, there is a large amount of data, beginners can look at program according to the data, and can appear the image)

产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2； 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50 ，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列） 改用HDB3码，画出前20个符号对应的波形 改用密勒码，画出前20个符号对应的波形 分别对上述1000个符号的波形进行功率谱估计，画出功率谱 改变信源“0”的概率，观察AMI码的功率谱变化情况(A length of 1000 random binary sequence, and " 0" with a probability of 0.8, " 1" with a probability of 0.2 the AMI code above zero, the pulse width of the symbol width of 50 , the waveform sampling rate Symbol rate 8 times, draw the top 20 of the waveform corresponding to the symbol (the first 20 and gives the source sequence) switch HDB3 code, the first 20 to draw a waveform corresponding to the symbol to switch Miller code, the first 20 symbols correspond to draw The waveforms of the symbol of the waveform 1000 power spectrum estimation, shown to change the source power spectrum " 0" , the probability of observation of the power spectrum of AMI code changes)

goertzel算法解码DTMF信号程序(algorithm for decoding DTMF signals goertzel program)

说明：  双馈电机数学模型，基于simulink，如果需要可以提供S函数的模型(Doubly-fed machine mathematical model, based on simulink, if necessary can provide a model S function)

数据统计与分析，基于matlab的函数实现，(some data statistical and data analyse in matlab ,)

matlab数学建模，matlab程序，实例代码皆有。包含着许多的建模算法程序实例(MATLAB mathematic modeling, matlab program)

本程序，对三维重建的结果调试已通过，得到很好的实验结果，方便大家学习。(This procedure, the results of three-dimensional reconstruction of debugging has passed, get a good result, we facilitate learning.)

基于三次指数平滑法的青岛港集装箱吞吐量预测 资料讲述了采用三次平滑法对吞吐量的预测细节 和思路(Based on the three exponential smoothing forecast container throughput of Qingdao port information about the use of three smoothing forecasts on the throughput of the details and ideas)

该程序在matlab环境下建立了三维曲线的拟合方法，该方法拟合效果较好。(The program in the matlab environment established a three-dimensional curve fitting method, the method fitting better.)
