What you need to know:

The demo shows how to achieve the function of cubic spline interpolation, and draws a graph that compares the normal curve and the spline curve.

this is a demo created by Qt creator, you can open the *.pro file to build this demo.

It's tested in the environment of Qt 5.15.2, MSVC 2019 64Bit.

Thanks to these third-party dependenies, include simple cubic spline interpolation library, qcustomplot.

你需要了解的内容：

这是一个实现样条插值的测试样例，绘制了一组插值前后的图进行对比。

本工程在 Qt creator中创建, 可以直接打开 *.pro file 进行查看和编译.

测试的环境为：Qt 5.15.2, MSVC 2019 64Bit.

项目建立在另外两个第三方开源库之上，simple cubic spline interpolation library, qcustomplot，一并表示感谢！
