三次样条matlab实现，插值就是已知一组离散的数据点集，在集合内部某两个点之间预测函数值的方法-Cubic spline matlab realize, interpolation is known to a discrete set of data points in the set between two points within a prediction function value method

三次样条插值求函数近似值；追赶法求解方程组。-Cubic spline interpolation for function approximation catching method for solving equations.

内含VB绘制三次样条曲线方法,并加入一个计时器,动态生成点并绘制样条曲线,形成动态锯齿图.-VB containing cubic spline curve drawing method, and add a timer, dynamically generated point and draw spline curves to form a dynamic zigzag map.
