《MATLAB神经网络30个案例分析》中的第9个例子，案例9 离散Hopfield神经网络的联想记忆—数字识别。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 9, 9 cases of discrete Hopfield neural network associative memory- digit recognition. Hope to have certain help to everybody! )

完全不调用matlab系统函数，编写canny边缘检测算法，适合初学者(Completely without calling matlab system function, write canny edge detection algorithm, suitable for beginners)

testpscad用以通过matlab来调用PSCAD程序，并执行PSCAD的模型，结束后关闭程序； testwrite是对PSCAD的模型进行修改的一个例子(testpscad matlab to call for the adoption of PSCAD program, and execute PSCAD model, after the close of the program testwrite PSCAD model is an example of modification)

用C语言编写MATLAB 函数, 主要用于DSP芯片上， 也可用于参考将C语言转换为汇编(Use the programming language C to write MATLAB function, histeq )

在Matlab中通过设计GUI，按下相应的卷积按钮，实现基本信号的卷积功能，并保存实验结果，返回主界面。(In Matlab through the design of GUI, press the button corresponding convolution convolution function, to achieve the basic signal, and save the experimental results, return to the main interface.)

這是本人自己寫的基於matlab的夫瑯禾費衍射仿真程序，希望能夠幫到有需要的人(This is my own writing based on the matlab Fraunhofer diffraction simulation program, hoping to help the needy。)

说明：  VMD是一种自适应、完全非递归的模态变分和信号处理的方法。(VMD is an adaptive, completely non-recursive method of modal variational and signal processing.)
