摘要: We present Gerschgorin-type eigenvalue inclusion sets applicable to generalized problems. Our are defined by circles in the complex plane standard Euclidean metric, and easier compute than known similar results. As one application we use our results provide a forward error analysis for computed of diagonalizable pencil.
