第一章
本文並非介紹 Mathematica 所有輸入與輸出的方式，而是集中在表示式的四種函數
呼叫語法，在我初學 Mathematica 時這些語法讓我十分困惑，因此我想在本書一開
始特別整理介紹。
函數呼叫法
（Functional Notation）
這是最常用的呼叫法，當你輸入
N[value,precision]
時，即是使用函數法呼叫
N
指令。
中置呼叫法
（Inx Notation）
中置法最常用在四則運算上，也可使用
~f~
語法以中置法呼叫任意
f
函數。
後置呼叫法
（Postx Notation）
階乘（
Factorial[]
）等數學算符使用後置法呼叫，前文曾使用後置法呼叫
N
指令，
任意
f
函數均可使用
//f
以後置法呼叫。
前置呼叫法
（Prex Notation）
負號等數學算符則使用前置法呼叫，使用
f@
語法可以前置法呼叫任意
f
函數。
以下使用
N
指令提供幾個範例。注意當使用前置法或後置法輸入多個引數時，須將
指令以純函數（pure function）語法表示，純函數中
#
代表引數，
&
則代表純函數
的結束，純函數語法等同於
Function[]
指令。
函數法
中置法
後置法
具引數的後置法
前置法
具引數的前置法
