讨论了二元数值积分的牛顿一柯特斯计算方法,并给出了计算的部分C语言代码,经过分析,该方法的时间复杂度为(m+1)·(n+1)·M·N。推而广之,该方法同样适用于多元数值积分的计算。
The Newton-Cotes method about how to compute two-dimensional numerical value integral is discussed.The author also offers its partial codes of computing program written in C language.He analyses the method and gets the conclusion that its time complexity is (re+1)·(n+1)·M·N.The method can also apply to multi-dimensional numerical value integral computing.
