利用虚拟软件Lab VIEW软件制作的曲线拟合程序，LabVIEW（Laboratory Virtual Instrument Engineering Workbench）是常用的虚拟仪器开发软件之一，可以方便快捷的完成程序的编辑。

1.绘制Bezier曲线，即根据给定的控制顶点，得到Bezier曲线。 2 绘制三次均匀B样条曲线，即根据给定的控制顶点，得到B样条曲线。 3 均匀B样条曲线拟合，即根据给定的型值点，得到B样条曲线。 4能够支持鼠标和键盘两种输入方式输入控制顶点和型值点； 5采用栈的方法，能支持无数个点的输入； 6程序界面及交互操作方面方便：如菜单，工具图表对话框； 7能修改输入的控制顶点（拟合均匀B样条曲线除外）； 8能预览输入点时的效果，即移动鼠标时，生成预览图象；

对于发动机实验建模有帮助吧 算是一种建模方法 如果能把发动机仿真做好就好了！

图形学完整课件，包括光栅图形学，图形裁剪，基本几何，二维几何，图形变换，三维几何，几何造型，光照模型，曲线与曲面，曲线拟合与双圆弧逼近，交互技术等

很好用的一款曲线拟合 插值小工具 界面简洁 操作方便

最小二乘法曲线拟合C语言可执行代码

这个软件是一个非常强大的根据数值找出其中数学规律的工具。对于给定的一组数据（x,y），它可以用上百种模型（函数公式）去匹配，找出其中误差最小的几个供你挑选,也可以自定义函数拟合。

ct. 18, 1995 v. 1.00 =========================================================================== + First release of CurveExpert 1.0. Oct. 26, 1995, v. 1.01 =========================================================================== New Features: + More attractive help file, with more keywords for searching + new help search facility available directly from CurveExpert Bug Fixes: + If a polynomial was already calculated, selecting another polynomial of a differing degree incorrectly pulled results from the cache instead of recalculating the curve fit. Fixed. + running two versions of CurveExpert is prevented, since two simultaneous instances cause stack faults. + if the data set is sorted, all interpolations are now marked invalid as they should be. + "Apply to All" did not necessarily force the current attributes of a graph to the current graph (only if the user clicks OK). Fixed. + The scrollbar did not get reset to the top when the user read in a new data file. Fixed. + The structure of the code has been undergone some major changes to ease porting to Windows 95 and Windows NT. I was exceedingly careful, but I hope this didn't introduce new bugs! :-) + For some reason, the help file didn't have any single or double quotes in it. This has been corrected, so it is now easier to read. + The help file was not terminated when CurveExpert was. Fixed. + The Window and Help menus were moved to more conventional positions on the menu bar. Nov. 4, 1995, v. 1.10: =========================================================================== New Features: + Previously undocumented logical functions can be used in the user-defined models. See the help documentation. + Current filename now appears in the title bar. + QuickCalc has been expanded to find the x-value, given the y-value. + Optimizations have
