摘要
给出了一种保形插值方法．通过插入一些新的节点，得到一种Ｃ２连续保形插值的五次样条函数．并且估计了保形插值样条函数的误差．
In this paper, a method for shape preserving interpolation is presented. By inserting some new knots, a C 2 shape preserving interpolating spline function of five degree is obtained. The errors of interpolating spline functions are estimated.
