摘要
对于给定的任何型值数组，本文通过插入新结点构造了Ｃ１连续的保形插值二次和三次样条函数Ｓ（ｘ），最后还讨论了单调保形的插值样条函数。
For any given sequence of data points,in this paper,a C1 shape preserving interpolating quadratic and cubic spline function S(x) by inserting some new knots are constructed by using Bernstein polynomails.The S(x) is simple and efficient to calculate.Finally the monotonic shape preserving spline function is also discussed.
