many problems in electrical engineering , such as the synthesis of linear n ports and the detection and filtration of multivariable systems corrupted by stationary additive noise , depend for their successful solution upon the factorization of a matrix valued function of a complex variable this paper presents several algorithms for affecting such decompositions for the class of rational matrices , i e , matrices whose entries are ratios of polynomials in the methods employed are elementary in nature and center around the smith canonic form of a polynomial matrix several nontrivial examples are worked out in detail to illustrate the theory
