应用MATLAB语言处理数字信号与数字图像，适合初学者学习(Application of MATLAB language processing digital signals and digital images, suitable for beginners to learn)

电力系统分析牛顿拉夫逊法就算潮流主程序及各个子程序合计牛拉法(Power Systems Analysis Newton Raphson even if the trend of the main program and each subroutine Total cattle Rafah)

PSOt is different of PSOrt, because you can choose differents mode of convergence

对数据进行卷积运算，只要导入需要处理的数据，即可运行程序，并给出计算结果图 (Convolution data, the data need to be processed as long as the import, you can run the program, and the results are given in Fig.)

本算法程序基于实测汽轮机振动信号进行了测试及性能分析。理论分析及仿真结果表明，AR模型谱估计算法在阶次合适的情况下，能够取得较好的方差及分辨力性能，适合于振动信号的功率谱估计，且AIC准则为确定合理的模型阶次提供了有效依据。(This algorithm based on the measured turbine vibration signal testing and performance analysis. Theoretical analysis and simulation results show that, AR model spectrum estimation algorithm in appropriate circumstances the order, the variance can achieve better performance and resolution, suitable for vibration signal power spectrum estimation, and the AIC criterion to determine a reasonable model order provides an effective basis.)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

说明：  计算给定矩阵的互信息，这时的相关性是利用互信息来判断，矩阵的形式为邻接矩阵(compute the mutual information of the given matrix such as the matrix the elements in it are 0 or 1.)

二次型的仿真，利用matlab实现，很好的例子啊(The second type of simulation using matlab to achieve a good example)

ti关于rf天线的设计、调试方法，13.56M精讲( ti on rf antenna design, debugging method, 13.56M succinctly)
