摘要
本文介绍了三次样条函数的基本概念 ,并利用三次样条函数二阶导数的线性关系 ,推导构造了一类三次样条函数 ,并结合实例用C语言给出了计算机求解方程组的过程。
This paper introduces the concept of cubic spline and makes use of its linear relation of the second order derivative to construct a kind of cubic spline. A concrete example is given to show how to solve the resulted group of linear equations with programming language C.
