David C. Lay 在美國加利福尼亞大學獲得碩士和博士學位。他是馬裏蘭大學帕剋學院數學係教授,同時還是阿姆斯特丹大學、阿姆斯特丹自由大學和德國凱澤斯勞滕大學的訪問教授。Lay教授是“綫性代數課程研究小組”的核心成員,發錶瞭30多篇關於泛函分析和綫性代數方麵的論文,並與他人閤著有多部數學教材。
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. Lay introduces these concepts early in a familiar, concrete Rn 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.

評分A first course in linear algebra is dramatically different from most mathematics courses that precede it.The focus shifts from learning computational procedures to digesting and mastering basic concepts that underlie the computations.To survive,you may need...
評分因为是考研学习LA 所以看了全国被普遍采用的那本紫色的同济LA教材,看着看着我发现那本书其实只是一本 线性代数公式大全,言简意赅到一个境界了,不适合我这样的普通智商的学生参读。 后来选择了这本LA&applications 觉得很不错。每章用一个introductory example开头 让人...
評分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...
