说明：  bp神经网络的学习和训练 matlab程序代码(bp neural network learning and training matlab code)

若一个三位自然数的各位数字的立方和等于该数本身，则称该自然数为水仙花数.此乃水仙花树的源程序(If one of you three-digit natural number and equal to the number of cubic itself, claimed that the number of natural numbers as daffodils. This is the source code tree daffodil)

这个题目是利用人工神经网络实现对数字调制信号的识别，建立BP网络，并用matlab编程实现仿真。(This topic is the use of artificial neural network to realize the identification of digital modulation signal, the establishment of BP network, and realize simulation matlab programming.)

EMD的程序要用到matlab的时频工具箱 matlab的工具箱的安装步骤： 1.解压下载的文件包，将tft/mfile复制到matlab的toolbox文件夹下 2.建立搜索路径，matlab->file->Set Path->Add Folder ->选择mfile文件夹复制到matlab的toolbox的路径->save->close 3.测试是否建立搜索路径成功，在matlab命令窗口打入：which fmsin 返回的结果是你放mfile的正确路径说明建立搜索路径成功。此时就完成了安装工具包的工作。(EMD program to use when the frequency of matlab toolbox matlab toolbox installation steps: Unzip the downloaded file package, copy tft/mfile to the toolbox matlab file folder 2 established the search path, matlab-> file-> Set Path-> Add Folder -> Select mfile folder to the toolbox matlab path-> save-> close 3 test whether to establish a successful search path in matlab command window enter: which fmsin The result returned is the correct path you put mfile instructions to establish a successful search path. This time to complete the installation kit work.)

用MIMO系统的空时编码仿真,matlab实现,性能对比分析(With space-time coding MIMO system simulation, matlab implementation, performance, comparative analysis)

这个是matlab分类工具箱，有大概三十多个matlab原程序，很适合大家下载使用(this classification is Matlab toolbox, probably more than 30 Matlab program, We are very suitable for downloading)

AES security algo with image processing

互相关与自适应滤波测量流速的比较研究，，分别讨论了互相关法和自适应滤波时延估计法测量流速(Cross-correlation to compare and measure the flow rate of adaptive filtering, respectively, discussed the correlation method and adaptive filtering delay estimation method measuring the flow rate)

自写曲率计算函数 ,关于非线性离散系统辨识，包含位置式PID算法、积分分离式PID。( Since writing the curvature calculation function, Nonlinear discrete system identification, It contains positional PID algorithm, integral separate PID.)

将Matlab下的M文件转换为DLL,在VC中调用.(M under the Matlab files into the DLL, the VC call.)
