摘要
在分析了基本样条函数插值基础上,对传统的三次样条函数作了推广。研究了任意一个插值点一阶导数和二阶导数的边界条件的样条函数解法。最后通过实例,说明了该计算方法。
Based on analysis of basic cubic spline interpolation,the traditional cubic spline interpolation is generalized.The methods are presented on the condition that the first derivative and second derivative of arbitrary node are given.At last,these calculation methods are illustrated through the examples.
