对Matlab的使用及其在相关方面的应用。(The use of Matlab and its related applications.)

VMWare是一个“虚拟PC”软件.它使你可以在一台机器上同时运行二个(VMWare is a virtual PC software, which allows you to run two at the same time on a single machine)

matlab线性代数的相关技术，适合初学者学习(matlab linear algebra related technologies, suitable for beginners to learn)

根据戴维南定理原理，用matlab语言编程实现其计算，使更运算方便(According to the principle of Thevenin theorem, using matlab language programming to achieve its calculation, which is more convenient operation)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

dv-hop程序，具有一定的参考价值！！！！(dv-hop)

波束形成就是从传感器阵列重构源信号。（1）、通过增加期望信源的贡献来实现；（2）、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复(From sensor array beamforming is reconstructing source signal.(1), by increasing the expected source contribution to achieve (2), by suppressing interference sources.Classic beamforming need observation direction (expected source direction).Blind beamforming is trying to not expect source direction information of source of recovery)

对EMD分解的改进，消除了EMD分解过程中的模态混叠现象，可以得到更准确的IMF分量(EMD decomposition for improvement, eliminating the EMD decomposition process modal aliasing, you can get a more accurate IMF components)

To finding an optimum parameter set using the evolutionary algorithm of Differential Evolution(This contribution provides functions for finding an optimum parameter set using the evolutionary algorithm of Differential Evolution. Simply speaking: If you have some complicated function of which you are unable to compute a derivative, and you want to find the parameter set minimizing the output of the function, using this package is one possible way to go.)

Approximate subspace-based iterative adaptive approach for fast two-dimensional spectral estimation
