Müller, Peter C. Comment on the remark by G. A. Kurina on a paper by P. C. Müller. (English) Zbl 1027.93017 Int. J. Appl. Math. Comput. Sci. 12, No. 4, 595 (2002). The author of the paper thanks G. A. Kurina for her valuable remarks [see the paper reviewed above (Zbl 1027.93017)] to P. C. Müller [Appl. Math. Comput. Sci. 8, 269-286 (1998; Zbl 0910.93047)] and states that her result simplifies the design of linear-quadratic optimal control for non-proper linear time-invariant descriptor systems.
