New Numerical Algorithm for Deflation of Infinite and Zero Eigenvalues and Full Solution of Quadratic Eigenvalue Problems
This article presents a new method for computing all eigenvalues and eigenvectors of quadratic matrix pencil Q (λ)=λ 2 M + λ C + K . It is an upgrade of the quadeig algorithm by Hammarlinget al., which attempts to reveal and remove by deflation a certain number of zero …
