三次样条插值程序演示。在SplineDemoView.cpp文件中的函数BOOL CSplineDemoView::ZSpline3()和函数double Spline3(double)是实现三次样条插值算法的核心函数。用VC6.0编译运行后，在窗口上由左至右点击鼠标左键设置一些点，然后点击鼠标右键即绘出穿过这些点的三次样条插值曲线。-Cubic spline interpolation procedure demonstration.

三次样条插值（简称Spline插值）是通过一系列形值点的一条光滑曲线，数学上通过求解三弯矩方程组得出曲线函数组的过程。-Cubic spline interpolation (hereinafter referred to Spline interpolation) is through a series of point-shaped curve of a smooth, mathematically by solving the three-moment equations derived

三次样条插值函数实现 运行后画出曲线图，并得到插值函数表达式。-spline3

构造了三次样条函数，并有MATLAB实现了其功能-Cubic Spline Interpolation Function
