线性代数导论

塞尔日·兰（Serge Lang，1927年5月19日－2005年9月12日）是美国数学家，因他在代数的工作和他编写的多本教科书（包括影响颇大的Algebra）而闻名。他的教科书定位于纯数学，以习题原创闻名。

This book is meant as a short text in linear algebra for a one-term course. Except for an occasional example or exercise the text is logically independent of calculus, and could be taught early. In practice, I expect it to be used mostly for students who have had two or three terms of calculus. The course could also be given simultaneously with, or im mediately after, the first course in calculus. 　　此书为英文版！
