摘要
Hermite 插值算法与节点的导数值密切相关,寻找节点的近似导数值——一阶差商,来构造 Hermite插值算法。并通过例题比较近似 Hermite 插值与 Lagrange 插值的异同.
Because Hermite interpolation algorithm is closely related to nodes' derivatives,this paper constructs Hermite interpolation algorithm by seeking the nodes' approximate derivatives-the first order difference,and compares approximate Hermite interpolation with Lagrange interpolation by instances.
