无穷域三重积分优化中心数值算法

AN OPTIMUM NUMERICAL METHOD OF CENTER FOR THE TRIPLE INTEGRAL OVER THE INFINITE REGION

本文采用步长三等办法给出三重积分f(x,y,z)dxdydz的优化中心数值积分法,它在迭代计算中免去重复计算,加速达到近似值精度。并给出了误差估计式。

Using trisection, this paper will give the optimality center algorithm method oftriple integral f(x,y,z)dxdydz and give the absolute error. In the course ofsubstitution this method can reduce the repetitions of calculating function values and accelerate the accuarcy of the approximate value.
