A Stable Approximate Methods for the Derivatives of Approximately Specified Functions of two Variables
【摘要】 提出了一种新的求近似已知二元函数的一阶,二阶偏导数的稳定近似算法,给出了误差估计,给出了数值例子.
【Abstract】 We present a new stable approximate methods for partial differentiation of specified functions,second partial differentiation of specified functions,the convergence rate of the approximate partial differentiation and second partial differentiation are derivated.Numerical experiments are presented.
