说明：  把在MATLAB中绘制的公式曲线、曲面上所有的点坐标数据都提取出来，若能让AutoCAD正确识别，那么我们就可以在AutoCAD中精确地绘制这些曲线、曲面了。 本文介绍了一种快速、精确地绘制各种公式曲线、曲面的方法，即在AutoCAD中通过调用经过Excel处理的MATLAB数据实现。
(Draw in MATLAB of formula curve, curved face up allly order to sit to mark datas to all withdraw, if can make AutoCAD correct to identify, so we can by the square draw these curve, curved faces in AutoCAD.This text introduced a kind of method that is rapid and by the square draws various formula curve, curved face and passed to adjust to use the MATLAB data realization of passing by the Excel processing in AutoCAD.)
