利用傅里叶变换对图像进行处理，分别用高通滤波和低通滤波对图像进行处理(image processing with fourier transform)

文件的读取 添加信息，删除信息，文件的储存(Read the file to add information, delete information, document storage)

说明：  matlab界面设计，八数码界面，搜索算法，爬山法(matlab interface design, eight digital interface, the search algorithm, hill climbing)

中频数字正交采样，并进行滤波，得出基带信号(IF quadrature sampling and filtering)

optimization algorithms

该程序可以用于所以现代控制理论里的关于系统的能观性、能控性等判断(the procedure can be used for so modern control theory Lane on the system observability and controllability such judgment)

Matlab ocr code which can be convert directly use as a source code

this is the source code for Matlab & simulink for digital communication. this folder contains all the matlab code in the textbook.

说明：  利用离散hopfield网络对图像进行去噪滤波，复原出效果较好的结果，要求初始存储的图像至少10幅以上，编程实现(Network using discrete hopfield image denoising filter, a better recovery result, the initial stored image requires at least 10 or more, programming)
