Linear Algebra and Its Applications,  by David C. Lay

书的内容简介：This book presents, in a reasonably clear manner, the concepts, formulas, and theorems related to linear algebra. Examples of linear algebra in economics and engineering help solidify these concepts. However, the book does not cover several types of matricies. For example, an assignment involved a population-change question involving Leslie matricies. Unfortunately, the Leslie matrix is not covered anywhere in the book. It would also be desirable to have a summary of the Invertible Matrix Theorem. Instead, the various parts of this theorem are scattered throughout the book. Otherwise, however, this book serves its purpose well- as an introduction to linear algebra.More advanced students will want a text with more thorough coverage.
