SVG无功发生器的matlab仿真，采用PI解耦控制。基于matlab 2014a编写。(SVG simulation of MATLAB reactive power generator, using PI decoupling control. Based on 2014a matlab.)

说明：  旋转不变性子空间（ESPRIT）类算法需要对阵列接收数据协方差矩阵进行特征分解。ESPRIT 类算法是利用接收数据协方差矩阵的信号子空间的旋转不变性，它利用各子阵的信号子空间之间的旋转不变性求出信号的入射角信息。(Rotation invariant subspace (ESPRIT) algorithms need to decompose the covariance matrix of array received data. ESPRIT algorithm is based on the rotation invariance of the signal subspace of the received data covariance matrix. It uses the rotation invariance between the signal subspaces of each subarray to obtain the incident angle information of the signal.)

C++ Primer Plus, Fourth Edition presents the ANSI C++ standard beginning with a discussion of the essential elements of C++ programming: loops, expressions, functions, and classes. It walks readers through the basics of object-oriented programming: classes, inheritance, templates, and exceptions, as well as the latest object-oriented programming techniques. C++ Primer Plus contains hundreds of sample programs. The friendly tone, concise programs, and end-of-chapter review exercises allow beginners to write their own programs immediately.

如何计算矩阵数据的协方差矩阵。还有在什么情况下只能计算均值、方差，而不能计算协方差，什么情下，只能计算协方差，但不能计算协方差矩阵。(How to calculate the matrix data covariance matrix. And under what circumstances can only calculation mean, variance, and not calculation covariance, what feeling, can only calculation covariance, but not calculation covariance matrix.)
