Nonsmooth analysis of eigenvalues

Mathematical Programming, 1999
Subdifferentials (limiting Fréchet, Clarke) of the composition \(f\circ \lambda \) of extended real valued permutation invariant functions \(f\) and the eigenvalue vector function \(\lambda \) of a symmetric matrix \(X\) are calculated using the transformation to principles axes.

Eigenvalue and eigenvector approximate analysis for repeated eigenvalue problems

AIAA Journal, 1992
The objectives are to present a method for eigenvalue and eigenvector approximate analysis in the presence of repeated eigenvalues and to present an alternate method for the eigenvector sensitivity equations. The method developed for approximate analysis involves a reparametrization of the multivariable structural eigenvalue problems in terms of a ...

Eigenvalues and troposcatter multipath analysis

IEEE Journal on Selected Areas in Communications, 1992
Performance predictions for troposcatter channels with multipath are developed using the eigenvalues in the Karhunen-Loeve representation of the tropo signal. Flat Rayleigh fading predictions, in the presence of jamming, are easily extended to multipath channels with this technique. >

Eigenvalue Analysis on Singularity in RBF networks

2007 International Joint Conference on Neural Networks, 2007
It has long been observed that strange behaviors happen in the gradient learning process of neural networks including multilayer perceptrons (MLPs) and RBF networks because of the singularities arisen from the symmetric structure in these models. The learning behaviors nearby are crucially dependant on the stability of the singularity. For RBF networks,

Random Eigenvalue Problems in Structural Analysis

AIAA Journal, 1972
A computerized Monte Carlo simulation is presented for calculating the statistical properties of the eigenvalues of a spring supported beam-column. The spring supports and axial force are treated as random variables ; the distributions of material and geometric properties are considered to be correlated homogeneous random functions.

The analysis of eigenvalue assignment robustness

IEEE Transactions on Automatic Control, 1995
The author shows that the results obtained recently in Wang and Lin (1992) are conservative. A new generalization which can overcome such conservatism is presented. >

Convergence Analysis of Newton-Like Methods for Inverse Eigenvalue Problems with Multiple Eigenvalues

SIAM Journal on Numerical Analysis, 2016
Summary: We provide in the present paper a corrected proof for the classical quadratical convergence theorem (i.e., Theorem 3.3 in [\textit{S. Friedland} et al., SIAM J. Numer. Anal. 24, 634--667 (1987; Zbl 0622.65030)]) of the Newton-like method for solving inverse eigenvalue problems with possible multiple eigenvalues.

Eigenvalue and eigenvector sensitivity and approximate analysis for repeated eigenvalue problems

32nd Structures, Structural Dynamics, and Materials Conference, 1991
A set of computationally efficient equations for eigenvalue and eigenvector sensitivity analysis are derived, and a method for eigenvalue and eigenvector approximate analysis in the presence of repeated eigenvalues is presented. The method developed for approximate analysis involves a reparamaterization of the multivariable structural eigenvalue ...
