Structured pseudospectra in structural engineering [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2005
AbstractThis paper presents a new method for computing the pseudospectra of a matrix that respects a prescribed sparsity structure. The pseudospectrum is defined as the set of points in the complex plane to which an eigenvalue of the matrix can be shifted by a perturbation of a certain size.
