quadratic eigenvalue
in [Matlab]

From: Bruno Luong on 6 Oct 2009 13:45 Does anyone know how I can obtain the right-most eigenvalue/vector (largest real eigenvalue) of a quadratic eigenvalue problem (QEP)? POLYEIG returns all the eigenvalues but I need only one. Additional information is that my QEP is monic. Bruno
