n阶行列式算法研究

Discussion on N-order Determinant Algorithm

行列式的计算方法有许多种,同一个行列式有不同的计算方法.为了较快地计算行列式,需要根据行列式的结构特点选择合适的方法.文章首先给出行列式的定义和性质,然后结合实例论述了行列式的8种计算方法.

There are many kinds of method for calculating the determinant,while the same determinants have different calculation methods.For fast calculating the determinant,the appropriate method is chosen through the structure characteristics of determinant.This paper first gives the definition and properties of determinant,and then discusses the eight kinds of calculation methods of the determinant.
