摘要
利用差分代替导数研究三角插值问题的基础上,讨论了奇数个等距结点上一类反周期函数的2-周期插值算子的逼近问题,得到了插值解的收敛性结论,是对相应的反周期函数三角插值问题的推广.
Based on difference replacing derivative to study trigonometric interpolation, a kind of 2-periodic interpolation of anti-periodic function is considered in this paper, some results are established on approximation of responding interpolation problem, which is a generalization of trigonometric interpolation of anti-periodic function.
