自适应算法的程序，用matlab语言编写，属于现代信号处理方法。(Adaptive algorithm of the program, with the matlab language, belongs to modern signal processing methods.)

模拟两个相干的的窄带信号。阵列的阵元数为10，快拍数为200，信号入射方向分别为20°，60°，阵元间距为入射信号波长的1／2，信噪比为20dB。分别用MUSIC算法和改进MUSIC算法进行仿真。仿真结果如下图所示(MUSIC algorithm is improved compared with the simulation of signal coherent MUSIC algorithm. Two coherent analog narrowband signal. Array element number of the array 10, the number of snapshots 200, a signal incident directions, respectively 20 °, 60 °, array element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB. Respectively MUSIC MUSIC algorithm and improved algorithm simulation.)

MATLAB连续潮流程序（9节点） （百度百科）连续潮流需要注意的问题： 1 连续潮流中两个重要的问题是：连续参数的选择和步长的确定。参数选取不正确或是步长不合理都会导致潮流不收敛。 2 连续潮流所求出的负荷裕度是针对特定网络状态和特定的负荷增长方式而言的。当增长方式改变或是网络结构或是参数发生改变后，连续潮流求出的负荷裕度是会改变的。 3 至今为止，出现了基于负荷增长的连续潮流、基于网络断线故障的连续潮流等。 (MATLAB continuous flow program (9 nodes) (Baidu Encyclopedia) continuous flow problems that need attention: A continuous trend in two important questions are: selection and step continuous parameter determining long. Parameter selection is incorrect or unreasonable step will not lead to the convergence trend. 2 continuous load margin is determined by the trend for a particular network status and specific in terms of load growth. When changing the growth mode or network structure or parameters are changed, the load margin is calculated continuous trend will change. 3 So far, there has been a continuous trend based on load growth, based on network fault and continuous flow and so on.)
