| 520 | 3 | |a We define the regularly structured pseudospectrum of a square complex matrix and describe its main properties. Using a difference one-dimensional convection-diffusion operator as an example, we explain why the regularly structured pseudospectrum is better than the ordinary pseudospectrum when we are interested in the question of how the minimal-in-magnitude eigenvalues of the finite-dimensional approximation of a differential operator can vary when its coefficients are perturbed. | |
