GSS第一篇博客文章 DA matlab 中的三次样条插值函数spline使用说明 spline(x,y,xx) matlab 中的三次样条插值函数spline使用说明 spline(x,y,xx) x,y是插值节点的坐标组成的向量(长度必须一致),xx为插值点的横坐标,由于三次样条插值函数有4n个未知数,而在内部节点上连续、一阶导连续、二阶导连续共3(n-1)...

This testcase fits a cubic spline to 8 x ) x ( f 3 − = along the x interval from 0 to 4. This problem is solved as an example in Lilley’s[1] notes. The cubic spline routine determines the same S values as the example. Figure 1 shows a plot of the function and the cu...
