perturbation matrix

基本解釋

Damage tends to be concentrated in a few structural members at the early stage, so the stiffness perturbation matrix tend to be in small rank.

The purpose of this paper is to study the additive perturbation of matrix eigenvalue. Some new absolute and relative perturbation bounds of matrix are obtained.
本篇文章主要研究了矩陣特征值的擾動，并給出了一些矩陣的絕對和相對擾動邊界。
The prevalent formula for nonzero perturbation matrix in the secular equation is gained by the perturbation theory in degenerate state and property of spherical harmonics function.
本文應(yīng)用簡并態(tài)微擾理論和球諧函數(shù)的性質(zhì)，得到久期方程中非零微擾矩陣元普遍表達(dá)式。
