Let $${\alpha}$$ be a square matrix of measures, and $${\left\{P_n(x; \alpha)\right\}_{n\geq 0}}$$ the associated sequence of orthonormal matrix polynomials satisfying the three-term recurrence relation $${x P_n(x; \alpha) = A_{n+1}(\alpha)P_{n+1}(x;

We study the asymptotic behavior of the ratio of two sequences of orthonormal matrix polynomials P n (with unbounded three-term recurrence coefficients) and [Ptilde] n , which are associated, respectively, to a matrix of measures and its perturbation

Orthogonal matrix polynomials on the unit circle and on a finite interval are completely determined by their reflection matrix parameters through the Szegő recurrences and by their matrix coefficients through the three-term recurrence relation, resp
