On Laguerre matrix polynomials. (English) Zbl 0990.33008

Summary: In this paper generalized hypergeometric matrix functions are introduced. Properties of Laguerre matrix polynomials and their connections with hypergeometric and Bessel matrix functions are established. Formulas for the generating functions of products of Laguerre matrix polynomials extending well-known formulas for the scalar Laguerre polynomials are given.
