Structured pseudospectra for matrix functions
Thomas Wagenknecht, Wim Michiels, K Green · Bristol Research (University of Bristol) · 2005
In this paper we introduce structured pseudospectra for analytic matrix functions and derive computable formulae. The results are applied to the sensitivity analysis of the eigenvalues of a second-order system arising from structural dynamics and of a time-delay system arising from laser physics. In the former case, a comparison is made with the results obtained in the framework of random eigenvalue problems
