说明：  MATLAB画图 目的是学会怎样使用MATLAB软件 来绘制各种图形 包括平面图和三维立体图(MATLAB drawing is to learn how to use MATLAB software to draw various graphics including floor plans and three-dimensional map)

matlab指令集，一般常用的指令都包涵(matlab code set)

用simulink搭建的自抗扰控制器中的跟踪微分器(The ADRC controller simulink structures of tracking differentiator)

已知被控对象的模型和期望传递函数分母多项式，用直接自校正控制方法对系统进行仿真(Known to the controlled object model and the desired transfer function denominator polynomial, with direct self-tuning control system simulation)

matlab环境下的灰色GM（1,1）完整程序，且带有部分说明(Grey GM matlab environment (1,1) complete procedures, and with a part)

说明：  快速傅里叶变换的子程序，直接在主函数中调用即可直接绘制信号的频谱图。(The subroutine of the fast Fourier transform can directly draw the spectrum of the signal by calling it directly in the main function.)

：自准直仪是比较常用的测角仪器，其原理是检测激光形成的图像光斑的中心之间的距离，通过 ) 个中 心的横纵坐标差来计算物体偏离的角度 ’ 利用迭代阈值和图像分割等方法将光斑图像进行预处理，然后将得到 的图像分别用重心法、圆拟合法和匹配法进行中心定位，并最终进行偏离角度的测定 ’ 文中介绍了所使用的几 种方法，并进行了仿真比较，结果表明，圆拟合法更有优势 ’ (: Is more commonly used since the collimator angle measuring instrument, the principle is to detect the distance between the center of the laser spot image formed by a) a horizontal and vertical coordinates of the center differential to calculate the deviation angle of the object ' iterative threshold and image method of segmentation, such as the spot image preprocessing, and then the resulting image with the center of gravity method, respectively, round contemplated legitimate and matching method center position, and eventually for the Determination of the deviation angle of ' paper describes the use of several methods, and simulation comparison, the results show that the circle fitting more advantageous' )

利用matlab编制灰色预测模型，通过少量的、不完全的信息，建立灰色微分预测模型，对事物发展规律作出模糊性的长期描述（模糊预测领域中理论、方法较为完善的预测学分支）。(Using matlab preparation gray prediction model, a small amount of incomplete information, the establishment of the gray differential prediction model fuzziness long description (fuzzy forecast field theory of the law of development of things, the more perfect branch predictions).)
