摘要
本文提出一种整体数值微分方法。此方系指同时求出所有节点上的导数值的方法,它的突出特点是照顾曲线的整体特性,既使函数值带有随机误差,也能够给出精度较高的数值导数值。
In this paper,a method of global numerical differentiation is given. What the so called global numerical method means the dervative at all nodes can be obtained simutaneously.The spcial feature of this method is to consider the global charcteristic of a curve.Even there are random errors with the function values,we acn. also, give an even more accurate values of the numerical derivatives. ?
