运用三次样条插值函数法对一条已知的折线进行圆滑（编程实现）-The use of cubic spline interpolation function of a line known for sleek (Programming)

this package implement a b spline algorithm in 1D 2D and 3D level. the Interpolation detail could be choose as use like.

在matlab中实现三种边界条件下的三次样条插值，以龙格函数为例(n the MATLAB, we implement three spline interpolation under three boundary conditions, taking Runge function as an example.)
