矩阵的秩在线性代数中的应用及其教学方法的探讨

摘要

With the rapid development of modern science and technology, the theory of economics is gettingrnincreasingly connected with mathematics. Especially, with the widely use of computer, linear algebra isrnbecoming more and more important in the social practice. In order to research linear equations, it forms anrnimportant definition-matrix. The rank of matrix plays a great role in linear algebra. The applications ofrnrank of matrix in linear algebra and the teaching methods about rank of matrix have been discussed in thernpaper.%现代科学技术的迅猛发展,经济学理论与数学结合的日益紧密,尤其是计算机的广泛使用,使得线性代数在人们的社会实践中扮演了越来越重要的角色.为了研究线性方程组,产生了一个重要的概念——矩阵.矩阵的秩在线性代数中扮演了重要角色.文章讨论了矩阵的秩在线性代数中的应用,也探讨了关于这个知识点的教学方法.
