《实用线性代数(图解版)》为英文原文中文注释版本,由一线教学任课老师在书中难点部分作出注释讲解。从几何直观的视角来审视线性代数的内容。

Content Description

本书区别于以往线性代数的书籍,内容新颖,编排独特,作者以几何视角讲述线性代数,通过二维平面和三维空间中的例子解释线性代数中的各种概念和性质。本书强调直观性以及知识点的背景,结合计算机中各种图形的变换来理解线性变换,注重可读性的同时突出数学的基本思想,将直观图形与数学证明进行了巧妙的结合。作者在书籍侧边空白处手绘200余幅示意图给出了相关概念的解释,更好的帮助读者理解。本书可供非数学类专业的学生及数学爱好者使用,亦可作为数学专业学生和教师的参考用书。
Author Description

杰拉德·法林(Gerald Farin),1979年于布伦瑞克大学获博士学位,著有"Curves and Surfaces for CAGD" (5th ed.), "NURBS" (2nd ed.)。同时他还兼任《计算机图形设计》主编。

Comments

★“这是一本鼓舞人心的书,书中涵盖了线性代数的所有内容,其中包含很多耐人寻味的例子,对于纯数学家了解更多关于线性代数的应用也很有意义”

Introduction

对于工科与经济类的大学生而言,“线性代数”是一门公共基础课,是必修的课程之一。常见的线性代数教科书大致有这样几个章节——行列式、线性方程组、矩阵、向量空间、特征值与特征向量、二次型。打开教材,迎面而来的就是计算与证明,鲜有知识点产生的缘由及其在实际生活中的应用。诚然,数学是一门抽象的科学,具有高度的概括性,但是这不代表数学教材就应该这样“斩头去尾烧中段”,干巴巴的毫无吸引力,冷冰冰地让人生畏。数学教育研究者们一直在呼吁数学文化的渗透,那么对于具体的一本教材而言,渗透什么内容?如何进行渗透?渗透到什么程度?我想,最基本的来说,至少要将知识的来龙去脉说个清楚。比如常见教科书开篇就是行列式的计算,那么学生肯定想要知道“行列式的本质是什么?为什么要学行列式?它在实际应用中的作用是什么?”在缺乏理解的基础上,就算学会了计算与证明,对知识的把握也是稀里糊涂的。这是件让人遗憾的事情。
本书,是一本弥补遗憾的书,是一本不同视角的书,是一本呈现知识点来龙去脉的书。本书按照先二维后三维的顺序呈现知识,使得知识形象化,便于理解。全书共分18章,第1章到第9章是二维情形,以独特的顺序与适宜的方式介绍了线性代数的基本知识点;第10章到第13章是三维情形,因此这四章是前九章的推广,但并不重复,各有仙机;第14章到第18章是高维情形,呈现了许多实际生活中的应用,同时也有助于读者抽象思维的发展。本书采用了非常规却符合认知的知识呈现顺序,以直观的、几何的叙述方式呈现内容,以大量的实际例证呈现应用。如果你不曾学过线性代数,阅读本书,会让你兴趣盎然地沉浸其中,顺理成章地掌握所有应掌握的知识点;如果你曾经学过线性代数,阅读本书,会让你不断地恍然大悟:“哦!原来这个知识点是这么来的!原来这个知识点是这么用的!原来这两个知识点竟然有这层关系!”如果你想要看一本有趣且有用的线性代数书籍,那么本书就是一个不可错过的上好选择!
