有限时域差分 FDTD （susan ） 程序(FDTD Using FDTD (susan) program)

This project proves to be a very useful home and office appliance as it eliminates the worry of user to open & close a door. In this project we have not operate door as we did manually as push and pull a door.Project circuit sens a human interference and accordingly it is open & close door. The term automated doors includes full powered automated doors such as those that are commonly used at supermarkets and transportation terminals and low energy and “power assist doors that are used in less demanding situations. Here it doesn’t require conventionally pull and push the door. So it can be useful for Handicap people. It is easy to use and affordable.

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改 第五章(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified Chapter)

搭建OFDM通信系统的框架，Relief计算分类权重，包含光伏电池模块、MPPT模块、BOOST模块、逆变模块。( Build a framework OFDM communication system, Relief computing classification weight, PV modules contain, MPPT module, BOOST module, inverter module.)

求双矩阵博弈的Nash平衡点，可以避免产生死循环。(Demand pairs of the Nash equilibrium point bimatrix game, can minimize the infinite loop.)

说明：  BP神经网络实现数据分类，实现语音特征信号的分类(BP network realize voice feature classification )

关于matlab环境下的ofdm系统，方便了解ofdm原理，理解方便。(Ofdm matlab environment on the system, easy to understand principles of ofdm, easy to understand.)
