说明：  是有关机器学习中讲密度估计的好资料，自己找了很久才找到的，国外人写的很容易懂，乐意分享(Machine learning is related to good information about density estimation, for a long time to find your own, and foreign people to write easy to understand, are willing to share)

说明：  BP神经网络异或问题 使用说明：打开文件夹中的BP.m文件，在matlab中运行此m文件，即可在command window中得出结果。压缩包内附说明文件 (XOR problem of the BP neural network for use: Open the folder in BP.m file, run this m file in matlab to the outcome of the command window. Compression package containing the documentation)

人脸识别，使用深度学习中的DBN算法进行人脸识别算法，数据集是ORL人脸数据集。(FACE Recognition, using the depth learning DBN algorithm recognition algorithm, the data set is a ORL face dataset.)

模拟退火粒子群算法，简单实用，非常好的程序(Simulated annealing particle swarm algorithm, simple, practical, very good program)

采用延时相乘法实现GPS信号的捕获，模拟产生三颗卫星的信号，然后通过延时相乘并进行频谱分析来得到伪码和多普勒频移(And delay phase multiplication analog GPS signal acquisition )

这是code使用说明,对大家比较有帮助，新手必备(This is the code for use)

温度PID控制功能块FB58使用入门 西门子自适应 以及C语言源代码(PID temperature control function block FB58 Getting Started Siemens adaptive and C language source code)

主要向大家介绍matlab当中的主要算法，有具体算法的应用，供大家学习交流。(Matlab which introduces the main algorithm, application specific algorithms for everyone to learn communication.)

计算了沿CMPL厚度方向，可以看出，CMPL的界面从第一个网格移动了1/4个网格，这是为了保证，CMPL更新的电场和磁场的数目相同。(The thickness direction along CMPL is calculated.It can be seen that the interface of CMPL moves 1/4 of the grid from the first grid to ensure that the number of electric and magnetic fields updated by CMPL is the same.)
