Structured EigTool Structured singular values and pseudospectra play an important role in assessing the properties of a linear system under structured perturbations. Structured Eigtool is a free Matlab interface for plotting structured pseudospectra. In particular, it supports the computation of real, skew-symmetric, Hermitian and Hamiltonian pseudospectra. Structured EigTool is heavily based on the EigTool [1] software package for plotting unstructured pseudospectra and inherits much of its interface.
