摘要 利用区间运算的相关理论,当Sylvester矩阵方程的系数矩阵不可对角化时,提出了计算其近似对称解及其可信误差界的算法,由此算法得到的误差界范围内必定存在一个精确对称解. Using the interval arithmetic theory,when the coefficient matrices of Sylvester matrix equation are not diagonalizable,an algorithm for calculating the approximate symmetric solution and its verified error bound are proposed,and there must be an exact solution in this error bound obtained by this algorithm.
