An explicit solution formula for the matrix modified KdV equation is
presented, which comprises the solutions given in Ref. 7 (S. Carillo, M. Lo
Schiavo, and C. Schiebold. Matrix solitons solutions of the modified
Korteweg-de Vries equation. In: Nonlinear Dynamics of Structures, Systems and
Devices, edited by W. Lacarbonara, B. Balachandran, J. Ma, J. Tenreiro Machado,
G. Stepan (Springer, Cham, 2020), pp. 75-83). In fact, the solutions in Ref.7
are part of a subclass studied in detail by the authors in a forthcoming
publication. Here several solutions beyond this subclass are constructed and
discussed with respect to qualitative properties.Comment: 10 pages, 6 figures, Proceedings of the Second International
