【摘要】 行列式是线性代数中的基本概念,无论是线性代数中的高深理论还是现实生活中的实际应用,都或多或少的与行列式有着直接或间接的关系。行列式的计算有一定的规律性和技巧性。本文针对行列式的结构特点归纳总结了行列式常用的几种计算方法,如升阶法、拆项法及递推公式法等,并通过具体实例说明这些方法在计算行列式中的应用,对帮助学生掌握不同形式的行列式的计算以及针对不同的行列式如何选取不同计算方法有一定作用。更多还原

【Abstract】 Determinant is a basic concept in linear algebra and has important applications in both the deep theory in algebra and the practical life.This paper introduces several commonly used calculating methods of determinants,such as ascending order method,disassembling term method and recurrence formula method,and illustrates their applications in calculating determinants through specific examples.It has certain effect on helping students master the calculation of different forms of determinants and how to choose different calculating methods for different determinants.更多还原
