一个绘制三次B样条的类，可通过型值点计算控制点，可进行拆分，可计算拟合误差-a cubic B-spline drawing of the category, through point-value calculation control points can be split, translate fitting error

三次样条和最小误差法进行曲线拟合，对于离散分布的点通过三次曲线拟合方法生成光滑曲线-Three times spline and minimum error curve fitting method, the distribution of point for discrete, through three spline proceed fitting connate into smooth curve

简单的三次样条曲线拟合代码！VS2005编译通过!-Simple cubic spline curve fitting code! VS2005 compiler through!

三次样条曲线拟合，可以将十个离散点拟合成一条曲线，曲线是C2连续。-Three spline curve fitting, you can put the ten discrete points into a curve, the curve is C2 continuous.
