Gaussian rule for integrals involving Bessel functions
收藏 引用
BIT NUMERICAL MATHEMATICS 2023年 第4期63卷 53-53页
作者: Denich, Eleonora Novati, Paolo Univ Trieste Via A Valerio 12-1 I-34127 Trieste Italy
In this work we develop the Gaussian quadrature rule for weight functions involving powers, exponentials and Bessel functions of the first kind. Besides the computation based on the use of the standard and the modifie... 详细信息

Evaluation of the use of the chebyshev algorithm with the quadrature method of moments for simulating aerosol dynamics
收藏 引用
JOURNAL OF AEROSOL SCIENCE 2012年 44卷 11-23页
作者: Upadhyay, Rochan R. Univ Texas Austin ICES Austin TX 78712 USA
The quadrature method of moments (QMOM) has been widely used for the simulation of the evolution of moments of the aerosol general dynamic equations. However, there are several shortcomings in a crucial component of t... 详细信息

Estimates of the trace of the inverse of a symmetric matrix using the modified chebyshev algorithm
收藏 引用
NUMERICAL algorithmS 2009年 第3期51卷 309-318页
作者: Meurant, Gerard 30 Rue Sergent Bauchat F-75012 Paris France
In this paper we study how to compute an estimate of the trace of the inverse of a symmetric matrix by using Gauss quadrature and the modified chebyshev algorithm. As auxiliary polynomials we use the shifted chebyshev... 详细信息

NUMERICAL algorithmS 1998年 第1-2期17卷 33-50页
作者: Roberts, DE Napier Univ Dept Math Edinburgh EH14 1DJ Midlothian Scotland
We consider polynomials orthogonal relative to a sequence of vectors and derive their recurrence relations within the framework of Clifford algebras. We state sufficient conditions for the existence of a system of suc... 详细信息

ON GENERATING ORTHOGONAL POLYNOMIALS
收藏 引用
SIAM JOURNAL ON SCIENTIFIC AND STATISTICAL COMPUTING 1982年 第3期3卷 289-317页
作者: GAUTSCHI, W
We consider the problem of numerically generating the recursion coefficients of orthogonal polynomials, given an arbitrary weight distribution of either discrete, continuous, or mixed type. We discuss two classical me... 详细信息
