摘要
在早期Hermitetian正定矩阵的研究结果的基础上,结合群逆和矩阵的分块,分析了Hermitian半正定矩阵的Weyl型相对扰动界,给出了相应的结果,从而得到一类矩阵特征值的新的扰动界.
Based on the early research on Hermitetian positive definite matrix and combined with the group inverse and block matrix, this paper analyzes Weyl-type relative perturbation bound of Hermitetian positive semi-definite matrices and presents the responding results. So the new perturbation bounds of eigenvalues of a kind of matrix are obtained.
