Resumen:
Given a weight matrix W(x) of size N on the real line oneconstructs a sequence of matrix valued orthogonal polynomials, {P_n}. We study the algebra   D(W) of differential operators D with matrix coefficients such that                                          P_n D=Lambda_n P_n, with Lambda_n in the algebra A of N x Ncomplex matrices. We study certain representations of this algebra,prove that it is a *-algebra and give a precise description of itsisomorphic image inside the algebra A^{N_0}.
