MATLAB code for generating faces using PCA. Displays all of the eigenfaces in a separate figure.

全选主元消元法解方程组，通过测试，可以自己修改方程组(Select principal component elimination method solution of equations)

说明：  计算短路电流（1相，2相，3相）。需要自己画出节点图并输入(Calculation of short circuit current (1 phase, 2 phase, 3 phase). Need to draw their own map and enter the node)

PULSED STRIPMAP SAR SIMULATION AND RECONSTRUCTION, u domain parameters and arrays for SAR signal, u domain parameters and arrays for compressed SAR signal, Fast-time domain parameters and arrays Resolution Parameters of Targets, SIMULATION, This code performs "narrow-bandwidth" digital spotlighting.To improve results, convert the code to "wide-bandwidth" , 2D BEAM PATTERN MATCHED FILTERING SLOW-TIME, DOPPLER SUBSAMPLING RECONSTRUCTION

说明：  利用matlab调用ansys模块进行计算，包含有例子(Using MATLAB to call ANSYS module for calculation, including examples)

本文对于非线性非高斯问题，提出了一种改进扩展卡尔曼滤波（NIEKF）新方法。该方法将迭代滤波理论引入到扩展卡尔曼滤波器方法中，有效地重复利用新的测量信息，还利用Levenberg-Marquardt 方法调整预测协方差阵以保证算法具有全局收敛性。实验结果表明，所提方法具有更高的估计精度，是一种效率较高、性能较好的跟踪方法。(This non-Gaussian for nonlinear problems, an improved extended Kalman filter (NIEKF) the new method. The method of iterative filtering theory is introduced to the extended Kalman filter method, the effective measurement of repeated use of the new information, also using Levenberg-Marquardt method to adjust the covariance matrix of prediction algorithm to ensure global convergence. Experimental results show that the proposed method has higher estimation accuracy, is a high efficiency, good performance tracking methods.)

说明：  s变换程序，是MATLAB编写的，可以用于地震数据处理方面(s transformation process, is prepared in MATLAB, can be used in seismic data processing)

说明：  对一个二阶模型模型进行脉冲响应辨识，并且通过搭建simulink模型取得了两组输入-输出数据，一组是在有高斯噪声的干扰下获得u1-y3，另外一组是在没有高斯噪声的情况下获得的u1-y1，对这两组数据进行基于haar小波基的脉冲响应辨识，与实际模型的脉冲响应相比较（注：三个excel表必须放在matlab/work文件夹下才能运行）(Second-order model to a model of impulse response identification, and achieved through building simulink model for two groups of input- output data, a Gaussian noise in the interference with access to u1-y3, another group in the absence of Gaussian noise of access to the u1-y1, these two sets of data haar Wavelet-based impulse response identification, and the actual model of the impulse response comparison (Note: Three excel table must be on the matlab/work folder to run ))
