本程序实现一个MATLAB辅助工具，你可以借助它，选择plot绘制出的各个图像数据，并且随意拖动它们。另外，它还有两个不同形状任意大小的绘图刷子。你使用这个工具选中点的时候，这些点被高亮，直到释放鼠标。另外你还可以在命令行下面调用这个工具，选择绘制的图像(This program implements a MATLAB aids, you can make use of it, select the plot to draw out each image data, and easily drag them. In addition, it has two different shapes of any size drawing brush. You use this tool to select points, these points are highlighted, until you release the mouse. Also you can call the following at the command line tool, select the image to draw)
