基于VC的三种端点条件的插值B样条曲线绘制，包括夹持端点，自由端点，抛物线端点，线性方程组的解法采用了追赶法。,VC based on the conditions of the three endpoint interpolation B-spline curve drawing, including the gripping end, the Liberal endpoint, the endpoint parabola, the solution of linear equations u

根据曲线上的型值点，用追赶法求反算出3次B样条的曲线控制顶点，再由3次B样条的系数矩阵设定均匀节点（50份）矢量求出50个点。 左键输入，完后右键完成输入，重新绘制,Under the curve data points, with catch-up method to calculate the anti-3 B-spline curve control points, and then 3 times by B-spline coefficient matrix of the node s

绘制NURBS的程序，有重点处理的功能，追赶法求的矩阵-Draw NURBS program， handling with double points well, catch up method to solve the linear system

埃特金插值算法和追赶法求解三对角方程组，都是自己通过看书自己编写的，我个人觉得还是具有通用性的。-The Aitken interpolation algorithm and the catch-up method for solving tridiagonal equations are own by reading a book I have written, I personally think it has the versatility.

三次样条插值程序，这个需要配合追赶法来求解一个线性方程组。-Cubic spline interpolation procedure, this need with the catch-up method to solving a linear equation.
