基于正交多项式下的数值微分任意阶稳定逼近
NUMERICAL DIFFERENTIAL FOR ARBITRARY ORDER APPROXIMATION STEADILY BASED ON ORTHOGONAL POLYNOMIAL
摘要
Abstract
In this paper, we investigate the numerical differentiation of higher order. Based on orthogonal polynomial theory, integral operator method is utilized. Using the proposed method we can estimate any order derivatives of approximately specified functions. The new method also generalized the result of the Lanczos’s.关键词
