摘要
本文讨论了二次样条插值的定解条件,在l_1模意义下给出了一类最佳二次样条插值的概念,以及寻找最佳二次样条插值的定解条件的方法.最后讨论了误差估计问题,并给出了实际算例.
In this paper is discussed the condition for determining solution to the quadratic spline interpolation problem by l_1 norm, and then are presented the concept of best quadratic spline interpolation and a simple method to determine such a best solution. Finally, the error estimates and some exciting numerical example are given.
