指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延，即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)

应用于变量选择的PCA 和 PLS 程序！利用它可以选出独立的变量数!在化学中很有用！(for variable selection procedures PCA and PLS! It makes it possible to elect independent variables! In Chemistry useful!)

This will give you some tips on how to build a gui using matlab, PDF file

This book is a short, focused introduction to MATLAB, a comprehensive software system for mathematics and technical computing. It will be useful to bothbeginning and experienced users.

对于一个动态系统dy/dt=-y(t)+x(t-m),m为一个时间滞后常量，x(t)、y(t)都是关于时间 t的函数，其中x是一个正态分布的数据集合，可随机产生，这样情况下，如何将系统情况 用样本点表示出来 (for a dynamic system dy/dt =- y (t) x (t-m), m for a time lag constants, x (t), y (t) are on the function of time t, where x is a normal distribution of data sets can be randomly generated, under these circumstances, how the system of sample points out)

这是VAD有关代码。也就是说为了在音声中找到activity voice 用GAET方法来决定阈值，然后判别了无音区间。(voice activity detection)

无静差转速负反馈调速系统的仿真模型。系统的给定信号设置为210rad／s，Pl调节器的KP=1.2， =40 其它的参统的参数和前面静差系统的参数一样。(No static error speed negative feedback speed control system simulation model. System of a given signal is set to 210rad/s, PL regulator KP = 1.2 = 40 the other parameters of system parameters and the front static difference parameters of the system.)

实现扩频里随机信号和伪码序列的产生，以及扩频信号的产生，用本地载波实现bpskt调制，在接收端用差分相干积分完成伪码捕获的相应MATLAB程序(Spread spectrum signal generated in the realization and pseudo random code sequence, and generate a spread spectrum signal modulation to achieve bpskt local carrier, at the receiving end with the completion of the pseudo-differential coherent integration of the corresponding MATLAB code acquisition program)
