A high order continuation method to locate exceptional points and to compute Puiseux series with applications to acoustic waveguides
Benoit Nennig, Emmanuel Perrey-Debain
A numerical algorithm is proposed to explore in a systematic way the trajectories of the eigenvalues of non-Hermitian matrices in the parametric space and exploit this in order to…
