Milovanović, Gradimir V.; Cvetković, Aleksandar S. Special classes of orthogonal polynomials and corresponding quadratures of Gaussian type. (English) Zbl 1272.33013 Math. Balk., New Ser. 26, No. 1-2, 169-184 (2012). Summary: In the first part of this survey paper, we present a short account on some important properties of orthogonal polynomials on the real line, including computational methods for constructing coefficients in the fundamental three-term recurrence relation for orthogonal polynomials, and mention some basic facts on Gaussian quadrature rules. In the second part, we discuss our Mathematica package OrthogonalPolynomials (see the authors [Facta Univ., Ser. Math. Inf. 19, 17–36 (2004; Zbl 1081.33001)]) and show some applications to problems with strong nonclassical weights on \((0,+\infty)\), including a conjecture for an oscillatory weight on \([-1,1]\). Finally, we give some new results on orthogonal polynomials on radial rays in the complex plane.
