线性代数(第2版)/付宇 内容简介
本书为教材，由长期在经济、管理类专业教授《经济数学》课程的一线教师在版的基础上，结合教学实践反复修订而成。本次修订是依据经济、管理类专业本科线性代数课程教学要求，参照近年来线性代数课程的实际教学经验及教材建设成果而成的，在内容编排、理论描述及例题习题选择上，做了进一步的调整和优化，以使全书逻辑性更强、主次更加分明、论述更加通俗易读。主要内容包括行列式、矩阵及其运算、线性方程组、向量组的线性相关性、相似矩阵及矩阵对角化、二次型等，它涵盖了经管类专业对线性代数知识的基本要求，并进行适当扩展以满足更深层次的学习。本书可供各高等院校经济、管理类各专业本科教学使用，也可供自学者、经管类考研者选读，具有较强的实用性。
