Published: 6 April 2021| Version 1 | DOI: 10.17632/dmvntgxscm.1


This data set contains the program code in MATLAB/GNU Octave for obtaining numerical examples in [1]. The data generated by this code are also included. The theoretical description of the method and of the initial data are provided in [1]. [1] Bondarenko, N.P.; Gaidel, A.V.
