自己编的EMODEL 的matlab程序，希望对大家有帮助!多指正!谢谢!(Own EMODEL of the matlab program, and they hope to help you! More correction! Thank you!)

Multiple Discriminant ysis

基于VB环境下的递推增广最小二乘法参数估计(VB Environment Based on Recursive Extended Least Squares Parameter Estimation)

PCA特征提取代码,对图像进行识别，并输出识别率，附详细说明(PCA characteristic extract code)

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

对采集到的振动信号进行EMD分解，得到一系列频率不同的经验模态函数IMF分量，可以用来滤波和提取原信号的特征。(The collected vibration signals of EMD, get a series of different frequency components of IMF empirical mode function can be used to filter and extract features of the original signal.)

假设在一个ad hoc网络中，移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道，测量接收到的信号功率X，其中X= I + N, I为接收到的干扰，N是噪声。移动节点只有在X＜INThre时，才可以发射。式中，INThre为背景噪声门限。 在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10。 (Assuming in an ad hoc network, mobile node s transmission power is always constant PTX. To send data to the mobile node always monitor channel, measuring the received signal power X, which X = I+ N, I was received interference, N is the noise. Mobile node only when X <INThre when it is fired. Where, INThre threshold for background noise. In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )

雷达回波的matlab实现,已经检测过，很好用，希望能帮到大家，谢谢。(Matlab implementation of radar echo，he has been tested, it is easy to use ,wish to help all friends,thank you )

说明：  实现了DCT的算法，用Matlab实现了任意维图像的DCT变换问题。(DCT algorithm implemented using Matlab implementation of arbitrary-dimensional DCT-image problems.)

说明：  电力系统中的牛顿拉夫逊算法实现潮流计算，Matlab实现，可以直接读取数据，目前110节点适用(Power System Newton Raphson power flow algorithm, Matlab implementation, you can read the data for the current node 110)
