用有限元算法 计算电磁场问题

说明：  burg算法的matlab实现，自己编写，有一定的参考价值(burg algorithm matlab realized, I have written has a certain reference value)

说明：  序列x（n）的间接法功率频估计用matlab来实现(sequence x (n) the indirect method of power frequency estimates using Matlab to achieve)

1-32是：图形应用篇 33-66是：界面设计篇 67-84是：图形处理篇 85-100是：数值分析篇 (1-32 are: application of articles 33-66 are graphic: interface design articles 67-84 is: is the graphics chapter 85-100: Numerical Analysis Section)

由matlab的commet函数改编而来，在原来基础上新增控制质点运动速度的功能(The commet by the matlab function adapted from the original particle motion based on the new speed control function)

本程序为产生多途信号，并对多个信号进行叠加，并混入一定信噪比的噪声。然后对得到的信号进行频谱分析和相关分析。(The procedure for producing multi-path signal, and the superposition of multiple signals, and mixed with a certain signal to noise ratio of the noise. Then the resulting signal spectrum analysis and correlation analysis.)

里面有很多使用的MATLAB代码，包括图形显示和计算源代码(There are a lot of use of the MATLAB code, including the graphical display and calculation of the source code)

说明：  d基于matlab的dtft算法，已通过验证，放心可用(dtft)

本程序是用于天线阵列波束波束形成的 LCMV算法，算法给出了误码率曲线，可以看出LCMV算法在高信噪比时误码率很小。 (this procedure is used for beam antenna array beam forming the Virus algorithm, the algorithm is given BER curves, Virus algorithm can be seen in the high signal-to-noise ratio at the bit error rate is very small.)

The activation function detected using MATLAB (Matrix laboratory) code

buck变换器仿真，直接可用，修改参数即可(buck converter simulation, directly available, you can modify the parameters)
