It is shown that they form an orthogonal system with respect to a matrix of measures, not necessarily symmetric. Moreover, it is stated the condition on the coefficients of the recurrence formula for which the matrix measure is symmetric.", keywords = "matrix orthogonal polynomials, recurrence formula, matrix of measures, block Jacobi matrices", issn = "1232-9274" }
