摘要
给出了矩阵指数的两个基本概念,然后对五种计算矩阵指数的方法从基本思想、解题步骤、实例演示和方法评析等角度进行了分析、归纳和总结。在具体计算矩阵指数时,可以根据不同的目的、不同的问题选择适当方法以简化计算。
In this paper,the related conception and nature of matrix exponential are firstly introduced.Then,the five kinds of methods on calculating matrix exponential are demonstrated.It includes the theoretical foundation,the calculating steps,the practice examples,and the advantage and shortcoming for each method of calculating matrix exponential.According to the difference of problems and purposes,we can simplify the complex degree of calculation if a suitable calculation method is concretely selected.
