说明：  绘制磁滞回线，模拟磁滞回线产生的过程，便于理论分析建模(Drawing hysteresis loops to simulate the process of hysteresis loops is convenient for theoretical analysis and modeling.)

又来了~~继上次之后的又一重磅出击，本程序也是图形填充(Here we go again ~ ~ Following the last after another heavy attack, the process is filled with graphics)

GDI source code. You can learn drawing in first

三次样条插值绘制光滑曲线，很有用的代码希望对大家有用(Cubic spline interpolation to draw a smooth curve, useful code hope to be useful)

说明：  图形绘制，可设置线宽、颜色、样式，通过本例将了解如何使用自定义画笔定义线体的颜色，线宽，线形等，以及如何为程序中添加选项菜单和选项设置对话框，如何使用标准颜色对话框，如何使用字体对话框，在选项对话框中实现预览功能。实现选项对话框和窗口类中的数据交换。如何改变对话框和控件的背景色，如何改变控件的文本颜色，对按钮控件的特殊处理。如何在窗口中显示一幅位图。(VC++ graphics rendering, can set the line width, color, style, through this example will learn how to use custom brushes defined line of body color, line width, line, etc., and how to add options for the program menus and options in Settings dialog box How to use the standard color dialog box, how to use the Font dialog box, implemented in the Options dialog box preview. Implementation Options dialog box and window class data exchange. How to change the background color of dialog boxes and controls, how to change the control' s text color on button controls the special treatment. How in the window display a bitmap.)

matlab图形逻辑处理程序，好程序共同分享。(matlab graphical logic handler, a good program to share.)

应用表面粗糙度曲线上寻找上下包络线，其过程：找到极大极小值，之后画出直线(envelop)

用Bresenham画圆算法绘制椭圆(with Bresenham algorithm mapping Circle Oval)

DFX格式的文件操作例子,可以读出由CAD绘制的保存为DFX格式的图片,附带大量注释(DFX format file manipulation example, can read out by the CAD drawing for the preservation DFX format photographs, Notes of a large number of fringe)

this file draw the nyquist diagram of multi input- multi output systems that they are such important kind of systems in control systems
