摘要
提出了三次Hermite分段插指函数的定义,得到了Hermite分段插指公式,证明了利用Hermite分段插指公式也可以避免出现Runge现象.
The definition of Hermite piecewise interpolation function in power exponent form has been proposed and Hermite piecewise interpolation formula in power exponent form has been obtained in this paper. The Runge phoneomenon can be avoided by using it.
