context: 上下文,有点像 域 (scope)

Every symbol has a full name with
fullname= Context`shortname,and the default  context is Global`

Context[symbol] return the context of symbol

在使用 symbol 时,如果省略context,系统会在$ContextPath 变量中搜索 symbol 定义或者第一次使用时所在的 Context。

$ContextPath=Join[$ContextPath,{context1`},...] 添加context1`到 $ContextPath
 

Begin["ContextA`"] to start a new context 


End[] to end the context

Package names are cotexts. And Mahtematica organizes the standard packages into a series of contexts(Algebra, Calculus, Geometry, Graphics and so on)
