摘要
本文给出了矩形域上二重积分的优化Taylor数值积分法,所得到的选代公式可避免重复计算,能加速收敛到给定的近似值精度,同时给出了相应的误差估计式。
In this paper, both the Taylor optimum numerical integration method about double integral over rectangular regions and the error formula are given. With the aid of the iteration method, we can avoid the repetition in calculating the function values and the convergence rate can be increased to the given precision the approximate value.
