[2D Graphic] SplineInterpolation-in-mfc DL : 0: 1、将三次样条插值功能封装成CCubicSplineInterpolation类，所采用的是第二类边界条件：在端点的二阶导数值为0. 2、基于对话框设计了使用界面，通过打开文件夹内的test.xls可以载入全部数据，并可利用上述三次样条类进行单点插值和全部插值。 3、经检验，该程序插值结果与matlab中： pp=csape(a,b, second ,[0 0]) result=ppval(pp,x0) 插值结果一致。-1, will be packaged into a cubic spline interpolation function CCubicSplineInterpolation class, which is used in the second boundary condition: The value of the second derivative is zero endpoint 2, dialog-based user interface design, by opening the file in the folder test. . xls can load all the data, and the use of the above classes of cubic spline interpolation and all single-point interpolation. 3, the test, the program matlab interpolation results in: pp = csape (a, b, ' second' , [0 0]) result = ppval (pp, x0) consistent interpolation results.
