样条后处理
计算样条、绘图、求最小值或过零点、积分或微分
拟合样条后,可以使用后处理方法来分析对数据的拟合是否准确。
使用 Curve Fitting Toolbox™ 函数执行绘图、评估或计算导数、积分和样条之间的差等任务。

- Postprocessing Splines
After constructing a spline, use postprocessing functions for tasks such as plotting, evaluating, or calculating derivatives, integrals and differences between splines.
