All the two important problems that the EM theory trys to describe and explain are propogation and radiation of EM wave, on the basic of Maxwell Equations. So we have to talk about the Maxwell Equations firstly  ,the greatest achievement in my opinio…

Weka EM covariance description 1: Dear All, I am trying to find out what is the real meaning of the minStdDev parameter in the EM clustering algorithm. Can anyone help me? I have not looked at the code, but I suspect that the minStdDev is used as the…

Markdown 学习笔记: Basics 原文:Basics. 了解Markdown格式化句法的要点 本页对如何使用Markdown提供了一个简单的概述.在"句法"页中对Markdown的所有特性提供了完整的,包含细节的文档.但Markdown应该仅通过浏览几个简单的例子就可以开始使用.本页中的这些例子写成了之前/之后的形式,展示出了Markdown的句法和对应的HTML输出. 另一个有用的方法就是试用下Markdown.Dingus是一个可以输入Markdown格式文本并转换成XH…

Today is a good day to start parallelizing your code. I’ve been using the parallel package since its integration with R (v. 2.14.0) and its much easier than it at first seems. In this post I’ll go through the basics for implementing parallel computat…
