§18.36(iv) Orthogonal Matrix Polynomials
►These are matrix-valued polynomials that are orthogonal with respect to a square matrix of measures on the real line. Classes of such polynomials have been found that generalize the classical OP’s in the sense that they satisfy second order matrix differential equations with coefficients independent of the degree. …37: 15.17 Mathematical Applications
