第二版前言
本书是在版的基础上，依据本科经济管理类专业对“线性代数”课程教学的基本要求，总结近年来一线教学的实践经验和学科建设成果，进行修订和增补而成的.
本次修订的基本思路是：在满足教学基本要求的前提下，适当调整了章节内容安排，使全书内容逻辑关系更为清晰，即把克拉默法则与线性方程组概念、消元法等知识合并在一起，并将线性方程组单列一章，使得方程组的知识体系尽量完整；同时关于线性方程组的解的结构，仍然和向量组的线性相关性结合讲授. 进一步完善了部分理论叙述和铺垫，适当减弱了理论推导和证明过程的要求，以使教材更加通俗易读. 另外，在版的基础上，全书重新编排了例题和习题，除了每章综合练习以外，每一小节后都有一个单独习题板块，以加强学生在学习过程中对基础知识的针对性训练.
本书编写分工如下：第1章主要由叶俊老师编写；第2章主要由汤红英老师编写；第3、4章主要由付宇老师编写；第5章主要由林映光老师编写；第6章主要由梁刚老师编写. 另外，付宇、叶俊、林映光老师还承担了全书的编排和校对工作，林旭东老师负责了部分章节的编排、校对工作.
本书在编写过程中得到了西南交通大学出版社的大力帮助，也得到了四川轻化工大学管理学院的大力支持，在此表示诚挚的谢意.
本书可作为本科院校经济管理类专业数学基础课教材，也可作为自学者参考教材.
由于时间和水平所限，书中难免存在不足，恳请各方专家和读者批评指正，我们将进一步修正和完善以提高教材质量.
