Abstract:
We give a new representation of the resolvent matrix and extremal solutions of the truncated Nevanlinna–Pick matrix interpolation
problem in the Stieltjes class functions via orthogonal matrix rational functions on $[0,\infty)$.
Keywords:
truncated Nevanlinna–Pick matrix interpolation problem, matrix-valued orthogonal rational functions, resolvent matrix.
