灰色理論之GM(!,1)模型，GM(1,1)的matlab源碼，可從生成一直計算到預測值(gray theory GM (! , 1) model, GM (1,1) Matlab source, has been generated from the calculated value of the forecast)

PID调节器结构简单、参数易于调整，当被控对象精确数学模型难以建立、系统的参数又经常发生变化时，应用PID控制技术，在线整定最为方便。 (PID adjustor simple structure, easy adjustable parameters, when the controlled object mathematical model is hard to build up, the parameters of the system and often changes, application of PID control technology, online setting the most convenient.)

说明：  模拟裂缝，通过预处理、相关法边缘检测，最终使用霍夫变换识别(Fracture simulation and recognition by Hough transform)

Matlab 符号运算是通过集成在 Matlab 中的符号数学工具箱（Symbolic Math Toolbox） 来实现的。和别的工具箱有所不同，该工具箱不是基于矩阵的数值分析，而是使用字符串来 进行符号分析与运算。实际上，Matlab 中的符号数学工具箱是建立在 Maple 基础上的，当 进行 Matlab 符号运算时，它就请求 Maple 软件去计算并将结果返回给 Matlab。(Matlab symbolic operation is integrated in the Matlab Symbolic Math Toolbox (Symbolic Math Toolbox) to achieve. And different from other toolbox, the toolbox is not based on numerical analysis matrix, but use a string for symbolic analysis and calculation. In fact, Matlab' s Symbolic Math Toolbox is built based on Maple, Matlab symbolic computation to the time when it requests Maple software to calculate and return results to Matlab.)
