摘要:
本文研究基于与权函数$w(x)= x^α e^{-x}$(支撑在区间$(0,z)$,$z>0$)相关联的正交多项式的Gaussian求积公式。使用modified Chebyshev算法来检验三项递推关系系数、零点与权重计算的精度,及其对参数$z$的依赖性。
英文摘要:
In this contribution we deal with Gaussian quadrature rules based on orthogonal polynomials associated with a weight function $w(x)= x^α e^{-x}$ supported on an interval $(0,z)$, $z>0.$ The modified Chebyshev algorithm is used in order to test the accuracy in the computation of the coefficients of the three-term recurrence relation, the zeros and weights, as well as the dependence on the parameter $z.$
