具体描述

Linear algebra is relatively easy for students during the early stages of the course, when the material is presented in a familiar, concrete setting. But when abstract concepts are introduced, students often hit a brick wall. Instructors seem to agree that certain concepts (such as linear independence, spanning, subspace, vector space, and linear transformations), are not easily understood, and require time to assimilate. Since they are fundamental to the study of linear algebra, students' understanding of these concepts is vital to their mastery of the subject. David Lay introduces these concepts early in a familiar, concrete R n setting, develops them gradually, and returns to them again and again throughout the text so that when discussed in the abstract, these concepts are more accessible.

作者简介

David C. Lay holds a B.A. from Aurora University (Illinois), and an M.A. and Ph.D. from the University of California at Los Angeles. Lay has been an educator and research mathematician since 1966, mostly at the University of Maryland, College Park. He has also served as a visiting professor at the University of Amsterdam, the Free University in Amsterdam, and the University of Kaiserslautern, Germany. He has over 30 research articles published in functional analysis and linear algebra.

As a founding member of the NSF-sponsored Linear Algebra Curriculum Study Group, Lay has been a leader in the current movement to modernize the linear algebra curriculum. Lay is also co-author of several mathematics texts, including Introduction to Functional Analysis, with Angus E. Taylor, Calculus and Its Applications, with L.J. Goldstein and D.I. Schneider, and Linear Algebra Gems-Assets for Undergraduate Mathematics, with D. Carlson, C.R. Johnson, and A.D. Porter.

Professor Lay has received four university awards for teaching excellence, including, in 1996, the title of Distinguished Scholar-Teacher of the University of Maryland. In 1994, he was given one of the Mathematical Association of America's Awards for Distinguished College or University Teaching of Mathematics. He has been elected by the university students to membership in Alpha Lambda Delta National Scholastic Honor Society and Golden Key National Honor Society. In 1989, Aurora University conferred on him the Outstanding Alumnus award. Lay is a member of the American Mathematical Society, the Canadian Mathematical Society, the International Linear Algebra Society, the Mathematical Association of America, Sigma Xi, and the Society for Industrial and Applied Mathematics. Since 1992, he has served several terms on the national board of the Association of Christians in the Mathematical Sciences.

读后感

最近想进修一下统计，遇到第一个难关就是线性代数，好多东西都忘得差不多了，只记得某年某月曾算过特征值和特征向量…… 依稀记得当年考研时候用的就是Lay老人家这本书的中文版，但想到自己已经是研究僧了，应该看看原版书了，于是决定厚颜无耻地去爱问上偷书。下...  

考研看的，其实指定用书是同济的现代，以前没学过线代，但是也没想过会这么难看，看得太痛苦了，所以后来换了这本"线性代数及其应用"，简直让我爱死它了，信心也大增，比国内的书好了不知多少多少倍，当时想起了王朔在“关于女儿”里面和记者的一段对话: 记者：您女儿是从小去...

认识一本好书就像遇见对的人，这本书就给我这种感觉，相见恨晚！ 先说那些小装饰，章前都有相关知识对应的生活应用实例+配图，虽然内容很少，但也很好地拉近了线代与生活的距离；一些注释会有一些参考文献的名字，偶尔去网上翻一下可以深入了解，甚至能挖到一些厉害的书，很开...  

作者在开篇就给了线性代数一个很新奇的定义：“从某种意义上说，线性代数是一门语言，你要像对待外语一样，每天都学。”书中有大量的应用实例，内容结构安排的很好，前几章就引入子空间，向量，线性变换的概念，还介绍了一下线性代数的核心思想和研究内容，而后面几章的内容都...  

这看起来不是机翻吗？表述方式一毛一样...看的难受不？我是难受死了，原版不折磨人，感觉是不是机械工业出版社的翻译书水平都不大行...还是我买的书就不太好？继续看原版吧，勿喷我，hhh，我只是表达不满，只是我的看法哟.........................................

Math 54... 真心觉得高中数学去死吧 为什么要有那种函数 圆锥曲线 导数搞在一起的题目 早点学些微积分 线代入门什么的不挺好嘛- -

我觉得蛮好的，简洁又很明白，习题有代表性。

这本教材由高斯消去法开讲至矩阵运算，行列式，向量空间，特征值（向量），正交与最小二乘法。与Strang的入门教材相比，Lay则多了几分严谨性且内容结构及其紧密。
