摘要
对两点和三点Gauss-Legendre公式进行复化,建立了两个新的数值积分公式,并分析了它们的积分误差和收敛阶.数值例子表明,我们的方法是高效的.
Two numerical integration rules are constructed by compositing the two-point and three-point Gauss-Legendre formulae,and integral errors and convergence order are also analyzed.Examples show that our methods are efficient.
