摘要:

基于Putzer算法, 将n维空间广义矩阵指数函数的计算转化为一维空间对应的齐次动力学方程求解问题. 结果表明, 该方法降低了空间维数及计算难度, 得到了广义矩阵指数函数的显示表达及算法.

关键词: 广义矩阵指数函数, 多项式, 动力系统, 卷积

Abstract:

We extended the method of Putzer to reduce a scalar differential equation to find a solution of the dynamical system. We reduced the  dimension and the difficulty of calculation and presented the explicit constructions for the generalized matrix exponential functions.

Key words: generalized matrix exponential function, polynomial, dynamical system, convolution product
