然后,将结果应用于中心对称结构的动力模型修正问题中,对给定的矩阵束,求出满足特征方程且具有中心对称特性的最佳矩阵束逼近。
2 . considering pencil of matrices with centrosymmetric could not satisfy characteristic equations in practice , it was necessary to study the centrosymmetric solution of the matrix equation least square problems , and to give pencil of matrices with centrosymmetric of the least squares problems in model updating
2 .考虑到实际问题中具有中心对称特点的矩阵束不一定满足特征方程,进而研究一类矩阵方程最小二乘中心对称解及其最佳逼近,从而给出模型修正中的最小二乘中心对称矩阵束。
