摘要
<正> 1.引言 考虑矩阵多项式: F(λ)=sum from j=0 to m(A_jλ~j),这里A_0,A_1,…,A_m均为n×n矩阵,λ为纯量.在工程实践中,上述问题归结为:求λ及非零n维列向量x。
This paper discusses the perturbation of latent values of matrix polynomials. Some inequ-alities Corresponding to both Wielandt-Hoffman theorem and Bauer-Fike theorem on the per-turbation of eigenvalues of a diagonalizable matrix are obtained.
