this is a sample for GUI in matlab.

说明：  用于识别图片中有多少个圆。用户只要用windows下的画图随便画若干个圆（不能交叉，但是可以包含）。保存成256色的bmp格式，该程序就能判断出你画的图片上有多少个圆(Used to identify the picture in many circles. Users only need to use the windows painting random drawing under a number of round (can not cross, but it can contain). Save as 256 color bmp format, the program can determine the picture you draw the number of round)

一款比较新的绘图软件的电脑书籍，比MATLAB更容易实现(A relatively new mapping software to computer books, is more easily achieved than in MATLAB)

说明：  自抗扰控制算法，适合初学者，算法简单，包括跟踪微分器，扩张状态观测器，非线性误差反馈率(Active disturbance rejection control algorithm, suitable for beginners, simple algorithm, including tracking differentiator, extended state observer, nonlinear error feedback rate)
