Tasić, Milan B.; Stanimirović, Ivan P. Simplifications of rational matrices by using UML. (English) Zbl 1299.65081 Facta Univ., Ser. Math. Inf. 28, No. 1, 75-86 (2013). Summary: The simplification process on rational matrices consists of simplifying each entry represented by a rational function. We follow the classic approach of dividing the numerator and denominator polynomials by their common GCD polynomial, and provide the activity diagram in UML for this process. A rational matrix representation as the quotient of a polynomial matrix and a polynomial is also discussed here and illustrated via activity diagrams. Also, a class diagram giving the links between the class of rational matrices and the classes of rational functions and polynomials is obtained.
