TWO-DIMENSIONAL NUMERICAL INTEGRAL CALCULATION DEVICE

摘要

PURPOSE: To calculate two-dimensional numerical integral values of a function by the two-dimensional numeric integral calculation device irrelevantly to integra tion order. ;CONSTITUTION: This device is equipped with a 1st calculating means 11 which sets section division points in an internal section having values as many as coordinate points of an object of internal integration as section division points of external integration when the coordinate points are supplied and calculates internal integral values according a prescribed integrating method by using the function values at those section division points, a 2nd calculating means 14 which calculates external integral values according to a prescribed integrating method by using the internal integral values when the 1st calculating means 11 calculates the internal integral values, a judging means 15 which judges the convergence of the external integral values calculated by the 2nd calculating means 14, and an actuating means 16 which sets section division points of external integration having larger values than before when the judging means 15 judges nonconvergence and actuates the 1st calculating means 11.;COPYRIGHT: (C)1994,JPO
