For systems which can be described by ut = Au, with a highly nonnormal matrix or operator A, the spectrum of A may describe the behavior of the system poorly. One such operator arises from the one-dimensional wave equation on a finite interval with a homogeneous Dirichlet condition at one end and a linear damping condition at the other. In this paper the… CONTINUE READING
