MUSIC算法是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成 (MUSIC algorithm is a feature space based on matrix decomposition method. From the geometric point of view, the observed signal space can be decomposed into signal subspace and noise subspace, it is clear that two spaces are orthogonal. Signal subspace to the data received by the array covariance matrix and the eigenvector corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector corresponding to the composition )

用4种方法绘出螺旋曲线上升的动态效果 x=cos(t) y=sin(t) z=t(Plotted using four methods increased the dynamic effect of the spiral curve x = cos (t) y = sin (t) z = t)

一天文学家要确定一棵小行星的运动轨道，他在其轨道内建立了以太阳为原点的直角坐标系，由开普勒第一定律知小行星的运动轨道为一椭圆，试确定行星的运动轨道。(One day in literature to determine the orbit of an asteroid, he set up in its orbit to the sun for the origin of the coordinate system, by Kepler s first law of motion track known asteroid is an ellipse, the orbits of planets.)

采用MATLAB语言编译的线性方程组求解函数，希望对大家有用(resolving overdetermined linear equations)

第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)
