Abstract

The authors regret several problems in the MATLAB code package in the supplementary material. These problems are fixed in the replacement package of the supplementary material. The replacement code is available also on GitHub: https://github.com/IdoSchaefer/SemiGlobalMATLAB The following problems have been found in the original code package: 1. Two m-files were missing. As a result, the program worked only for the Arnoldi algorithm, and not for the Chebyshev algorithm. In particular, the examples in the “examples” sub-folder did not run. In the replacement package the missing files were added.2. Several bugs which appear in rare situations were found: a. The program crashed when the final time of the propagation is 0.b. The estimations for the time expansion error in a backward propagation gave negative values instead of positive ones.c. In the case of an inhomogeneity in the differential equation, the source term has been always evaluated at [Formula presented] at the initial time, even when a different initial time was specified.The mentioned bugs do not affect the results presented in the paper, or those of the examples in the “examples” sub-folder. The bugs were fixed in the replacement package.Several additional changes have been made in the replacement package: 1. Minor modifications to the program SemiGlobal.m have been made.2. We added demonstration of the application of SemiGlobal.m for reproduction of the results presented in the paper.The authors would like to apologize for any inconvenience caused.
