摘要
考虑一类来自过阻尼系统的二次矩阵方程数值求解问题,针对方程系数矩阵的结构特点,设计了一种快速求解方程的迭代算法,给出了这类算法具体的迭代格式和收敛性。数值实验表明,提出的算法能够有效地求解此类方程具有实际意义的解。
Aiming at the numerical solution of quadratic matrix equations in an overdamped system,and based on an analysis of the structural properties of the coefficient matrix of the equation,an iterative algorithm for a quick solution of the equation has thus been proposed,with its specific iterative format and convergence subsequently given.The numerical experiments show that the proposed algorithm is of practical significance for the effective solution of this kind of equation.
