Computing the distance to continuous-time instability of quadratic matrix polynomials
Malyshev, Alexander; Sadkane, Miloud (Journal article; Peer reviewed, 2020)A bisection method is used to compute lower and upper bounds on the distance from a quadratic matrix polynomial to the set of quadratic matrix polynomials having an eigenvalue on the imaginary axis. Each bisection step ... -
Sur la distance à l'instabilité de polynômes matriciels quadratiques / On the distance to instability of quadratic matrix polynomials
Malyshev, Alexander; Sadkane, Miloud (Peer reviewed; Journal article, 2019-06-27)A bisection method is developed for computing the distance to instability of quadratic matrix polynomials. The computation takes rounding errors into account.
