直接将坐标展在cad中和南方cass中的一功能相似，只是直接在cad中就直接能实现该功能。(Directly coordinate the event in cad and in the South cass of a function similar to, but directly in the cad on directly to achieve this feature.)

有关绘图的非常有用的学习资料，用它学习matlab，从入门到精通，面面俱到(Drawing on the very useful learning materials, use it to learn matlab, from entry to the master, everything)

分析计算大规模数据的线性度的一个小程序，可绘图，m文件(Linearity analysis and calculation of data, can be a drawing, m file)

说明：  lisp学习应用 这个挺好的 建议大家学习一下 反编译也不错 就是没工具 那就下一个吧 还挺麻烦 随便上传一个小程序 呼伦一下吧(lisp CAD vba would did like a little piggie ?I like the fat pig,so I will buy a big fat pig and a little doggie .)

DDA算法画直线，可以实现在网格下逐点画直线。(DDA algorithm for drawing straight lines, can be achieved in a grid-by drawing straight line.)

绘图板软件，实现了文件打开，矢量保存，各种线和图形的绘画，颜色的更换。(it is a paint pad,you can use it to change your color,your paint,and can save yours.)

贝塞尔曲线绘制源码，例程程序调用API函数PolyBezier根据坐标点画贝塞尔曲线，或根据贝塞尔曲线特点在画板上画直线连接各坐标点。(Bezier curve drawing source , routine program calls API function PolyBezier Bezier curve based on the coordinates stippling , or draw a straight line on the drawing board in accordance with the characteristics of the Bezier curve connecting the coordinate points .)

DDA.中点。Bresenham画线算法。(failed to translate)

服装CAD源代码，可以进行bspline的打断分割割，裁减操作，而且还可以解析shx字库，进行标注等。 (Garment CAD source code can be bspline split the interrupted cut cut operation, but also can resolve shx font marked.)

中心点垂直磁场，使用matlab已有的erf误差函数，图形已绘制，绘制偏b比偏t的曲线(The center point of the vertical magnetic field using matlab existing erf error function, the graphics have been drawn, draw partial b than partial t curve)
