波达方向（DOA） 估计的基本问题就是确定同时处在空间某一区 域多个感兴趣的信号的空间位置(即多个信号到达阵列参考阵元的方 向角)。最早的也是最经典的超分辨率(DOA)估计算法是著名的多信号 分类（Multiple Signal Classification） 法,简称 MUSIC 算法,它是 一类经典的基于特征结构分析的空间谱估计方法。该算法利用了信号 子空间和噪声子空间的正交性,构造空间谱函数,通过谱峰搜索,检测 信号的 DOA。(The basic problem of DOA estimation is to determine the simultaneous location in a certain region of space. Spatial position of multiple interested signals in the domain (i.e. the direction of multiple signals reaching the array reference elements) Directional angle). The earliest and most classical super-resolution (DOA) estimation algorithm is the well-known multi-signal.Multiple Signal Classification, referred to as MUSIC algorithm, is A classical spatial spectrum estimation method based on eigenstructure analysis. The algorithm utilizes signals. The orthogonality of subspace and noise subspace, the construction of spatial spectral function, through peak search, detection DOA of signal.)

very good program in orbit mechanics

该SIMULINK模型为模拟高压分相开关、分相故障、高压线路等值模型。同时仿真了发生短路时，可以模拟短路电流(The SIMULINK model to simulate high pressure phase switch, phase failure, high voltage line equivalent model. At the same time simulation of a short circuit, short-circuit current can be simulated)

c++实现UPnP设备发现功能，对初学者非常有用，走出第一步。实现设备发现后，控制功能的原理比较简单，工作量不大。(UPnP device discovery via c++， useful with beginners.it s the first step. After discovery,control is easy and simple.)

说明：  这个程序是一本美国的数值方法教材上提供的，程序清单如下(the procedure is a numerical method for the United States to provide the materials, procedures following list)

这是另一个相关程序，求解传热系数的基本思想相同，只是温度的检测点不同。(This is another procedure, solving heat transfer coefficient of the same basic idea, but the detection of temperature difference.)

This code is used for trajectoru tracking using EKF.
