在[0 2π]范围内绘制以Y轴为对数的二维曲线图， y=|1000sin(4x)|+1(describe )

说明：  DE算法 经典的算法，来自于英文文献，适于研究DE算法(Simple DE algorithm )

steffenson迭代法Matlab源码(Matlab source steffenson iterative method)

Richmond法分析半波振子的电流分布与解析法对比，方向图，增益(Richmond half-wave dipole analysis of current distribution and the analytical method comparison, pattern, gain)

八单元线阵的DOA估计的MUSIC算法实现。可以看出music方法分辨率较高。这里用的是36度方向下的weight,自己也可以尝试其他的天线weight值。 (eight modules Array DOA MUSIC algorithm. Music can be seen higher resolution method. Here is the direction of 36 degrees under the weight, they could also try to the other antenna weight values.)

本程序是用经验模态分解(EMD)算法检测VF信号的，该算法的灵敏度和特异性都达到了90 以上。(This procedure is used empirical mode decomposition (EMD) algorithm to detect VF signals, the sensitivity and specificity of the algorithm has reached more than 90 .)

采用线性滤波法即AR法模拟脉动风速,计算时间短，模拟效果好(Linear filtering AR simulation fluctuating wind speed)

该算法为最小均方误差滤波，对输入信号进行滤波，输出滤波后的波形和误差(The least squares algorithm, the input signal is filtered, and the filtered output waveform error)
