工科线性代数必需的三项改革—介绍《实用大众线性代数(MATLAB版)》教材及其慕课

Three Necessary Reforms in Linear Algebra for Engineering—Introduction to Book “Applied Linear Algebra with MATLAB”

摘要: 用逆向思维的方法，从大量工程应用题解的实践中总结出：使用线性代数的第一个难点是“计算太复杂”，因此计算机化是改革的第一重点；第二个重点是必须能证明用线性代数解题是学科交叉的创新，比用旧方法好得多；第三个重点是要扬弃繁琐无用的数学理论，选择真正有用的内容，使大一学生能够接受。根据这三条原则，写成了《实用大众线性代数(MATLAB版)》教材，并制作成慕课(MOOC)播放，深受好评。

Abstract: Using reverse thinking method, dozens of engineering linear algebra problems were solved. We found that the biggest obstacle is the complexity of calculation, so computerization is the first key point. Showing innovative solutions using computer surpassing the old ones in engineering courses is the second point. The third is the deletion of useless mathematics theory. According to these prin-ciples, the textbook of “Applied Popular Linear Algebra with MATLAB” and its MOOC was launched.
