Pchip hermite

Splet但是直接使用Hermite插值得到的多项式次数较高，同样存在龙格现象，因此常用分段三次Hermite插值多项式(PCHIP函数) 找需插值点最近的四个点构成三次函数，来对该点进行插值 实现：matlab中PCHIP函数 4.三次样条插值 Spletpchip和spline区别. pchip指分段三次hermite插值，调用形式：pchip (x,y,xx) xx为插值点. spline指三次样条插值，调用形式：源自文库pline (x,y,xx) xx为插值点. spline提供的函数s (x)的构建方法和pchip里面的函数p (x)完全相同，只不过在X (j)处的斜率的选择方法不一样，spline函数 ...
