电力系统的短路计算过程繁琐工作量大，采用计算机编程计算不但省去了繁琐的人工计算，而且精确度高。我选用matlab作为编程语言，因为Matlab对处理数组有着其它编程语言所无法比拟的优越性。此外matlab中的GUI界面直观简单，而且制作过程并不复杂。(power system short-circuit the cumbersome process of calculating workload, calculated using computer programs not only save a cumbersome manual calculation, and high precision. I use Matlab as a programming language, because Matlab have to deal with an array of other programming languages are incomparable superiority. In addition Matlab the GUI interface is very intuitive and simple, but the production process is not complicated.)

SG5点滤波，主要用于高光谱数据处理的滤波(SG5-point filter, the main data processing for high spectral filtering)

esignatedlog perd，用于计算和

一个关于注水svd预编码的算法程序，一定可以用(Svd on the injection of a pre-coding algorithm program will be able to use)

粒子群做非线性模型的参数估计，已检测很好用(nonlinear parameter estimation)

纯ALOHA协议的源程序。分为主程序和调用程序(The source of the pure ALOHA protocol. Divided into the main program and the calling program)

利用方位角，仰角和直线距离画三维散点图。通过转化来求解(Using azimuth, elevation and draw a straight line from the three-dimensional scatter plot，by converting to solve)

简单的ofdm信号，主要为信号的建立过程，另有瑞利衰弱信道的代码(The simple OFDM signals, mainly for the establishment process of the signal, otherwise Rayleigh Fading Channels code)

改进的分段线性表示方法，含有四种基本算法，自顶向下，自底向上，滑窗，以及滑窗式自底向上算法。是流行的降维、分类算法。改进之后，所得出的线段是连续的，解决了离散线段带来的不便。(Rewised PLR algorithms inclusing four basic methods: top down, bottom up, sliding window and sliding window bottom up. PLR is a popular algorithm for classification and demension reduction. )
