EOF分解,简单易行，十分有效，输入相应变量即可得到，还可以出图(EOF decomposition is simple and efficient, and can be obtained by input corresponding variables.)

说明：  应用matlab完成邻域平均法来实现数字图像去噪(Digital image neighborhood average method denoising realization )

说明：  用于计算色散,延迟不通 ,透镜的不同口径(compute dispersion)

辐射边界和定温边界条件下，二维矩形平板的温度场数值模拟。(Radiation boundary and constant temperature boundary conditions, two-dimensional rectangular plate temperature field numerical simulation.)

这个程序主要是实现QAM的调制和解调的过程。(This procedure is mainly the implementation QAM modulation and demodulation process.)

说明：  MATLAB是由美国mathworks公司发布的主要面对科学计算、可视化以及交互式程序设计的高科技计算环境。它将数值分析、矩阵计算、科学数据可视化以及非线性动态系统的建模和仿真等诸多强大功能集成在一个易于使用的视窗环境中，为科学研究、工程设计以及必须进行有效数值计算的众多科学领域提供了一种全面的解决方案，并在很大程度上摆脱了传统非交互式程序设计语言（如C、Fortran）的编辑模式，代表了当今国际科学计算软件的先进水平。　(MATLAB is a U.S. company' s main face mathworks scientific computing, visualization and high-tech interactive computing environment programming. It numerical analysis, matrix computation, scientific data visualization and nonlinear dynamic systems modeling and simulation, and many other powerful features in an easy to use integrated Windows environment for scientific research, engineering design and the need for effective numerical calculation many fields of science provides a comprehensive solution, and largely out of the traditional non-interactive programming language (such as C, Fortran) of the edit mode, on behalf of the current international advanced level of scientific computing software.)

基于改进的PI模型对非线性曲线进行拟合，二次寻优算法进行参数辨识，用逆模型前馈补偿(Based on the improved PI model, the nonlinear curve is fitted, and the second optimization algorithm is used to identify the parameters, and the inverse model feedforward compensation is used.)
