these packages is for generating random data

LMD算法，对信号进行LMD分解，分解的层数可由自己定，并且能得出分解波形~(LMD algorithm, LMD decomposition of the signal,the decomposition of the layers can be set for oneself, and can come to break down waveform ~)

这是一种高阶滑模的船舶姿态控制方法，经过此程序可以实现船舶航行时的姿态控制。(a kind of higher-order sliding mode controller design for ship attitide control)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)

erms 均方差图像误差检验，用于两张图片之间的对比(erms mean square error test images)

计算信号的谱特性，包括频谱特征及功率谱特征。(Calculate the spectral characteristics of the signal, including spectral characteristics and power spectral features.)

说明：  我不多说废话，这是一个完整的TURBO码的编解码程序，对想做信道编码仿真的人绝对利好，该死的20个字(I will not nonsense, it is a complete code of TURBO codec procedures, right wants to channel coding simulation of absolute good, damned 20 characters)

EM algorithm using matlab

matlab的核密度工具箱，非常实用，简单易用。(nuclear density matlab toolbox, very practical, easy to use.)

PSO algorithm for solving basic question. It combine with c1 and c2, which their sum are between 0 to 4.
