Abstract

Summary This publication supplements the article "Computing eigenfrequency sensitivities near exceptional points" with tabulated data as well as matlab and python code that enables reproducing the results. The article presents a semi-analytical solution for a simple system that is used to validate a numerical framework. Structure The scripts refer to the figures in the paper as indicated by their names. They reproduce the figures based on data in corresponding files. If the files with numerical results are removed, the matlab scripts reproduce them. With the python script the semi-analytical results can be generated. Requirements JCMsuite (we used version 6.0.10) MATLAB (tested with version R2019b) In order to run the simulations with JCMsuite you must replace corresponding place holders with a path to your installation of JCMsuite. Free trial licenses are available, please refer to the homepage of JCMwave.
