• 論文の詳細を見る

• The following three new ideas are introduced to adaptive Newton-Cotes quadrature methods. (1)Refinement of error estimation. (2)Relaxation of convergence criterion. (3)Treatment of extraordinary points. By virtue of these improvements, reliability, efficiency and versatility of the methods are largely enhanced. The adaptive Newton-Cotes 9-point quadrature subroutine DAQN9 incorporating these improvements is described and its performances in comparison with well-known subroutines are shown.
