3.0 導論
高等數學豐富的抽象結構與形式使得數學超越了數字的領域，本章包含各種資料結構與
演算法相關的訣竅，以解決線性代數、張量運算、集合論、圖論及計算機科學等領域的
問題，通常這些資料結構均建構在串列（list）基礎上，以串列表示集合、向量、矩陣與
張量有很多好處，因為 Mathematica 提供許多通用的串列操作指令，可用來實現這些結
構的計算。串列、集合或張量在數學上是極為不同的抽象物件，而它們相異之處在於運
算方式而非資料儲存方式。[Page-85]
串列相關指令
Mathematica 大 部 分 資 料 結 構 基 礎 是 串 列， 除 非 你 熟 悉 串 列 處 理， 否 則 若 要 以
Mathematica 進行高階運算是相當困難的，因此本章由串列基本處理開始。Mathematica
串列的建立方式是
List[elem1,elem2, ...,elemN]
，或者更常用的方式是以大括號建
立：
{elem1,elem2,...,elemN}
，元素型態沒有任何限制，可為各種型態的混合，如數
字、字串、指令、串列與其他 Mathematica 中的任意物件（如圖形與音訊等資料）。
了解串列的第一件事是如何建立它，最常用的
Table
指令負責串列建立，以下提
