本源码目的在于查找一幅图像中个图形的重心，基于matlab，找出重心后标记出来，并显示。(The Source aims to find an image in a graphics core, based on matlab, after the marked identify the focus, and display.)

三维子空间music 方位角定义为与x轴的夹角，俯仰角定义为与z轴之间的夹角,俯仰角在0—90度，方位角0-180. 分辨不相关的两个角成功概率/估计偏差与SNR 最后进行谱峰搜索(Dimensional subspace music is defined as the angle and azimuth angle, pitch angle is defined as the x-axis and z-axis between the pitch angle of 0-90 degrees in azimuth 0-180 distinguish two unrelated probability of success angle/estimation error and SNR Finally peak search)

add pink noise to signal with certain SNR

在平滑信号中加入高斯分布的白噪声，然后用db4小波函数进行多尺度分解，滤除白噪声，将滤波前后的图进行对比(Add the Gaussian distribution of the white noise in the smoothed signal, and then multi-scale decomposition db4 wavelet function, the filtered white noise, comparing before and after filtering)

调频立体声接收机模型 对相应的立体声解码过程进行建模和仿真。设左右声道的信号分别为1000Hz和2000Hz的单频测试信号。 (FM stereo receiver model for the corresponding stereo decoding process modeling and simulation. Set left and right channel signals were 1000Hz and 2000Hz single frequency test signal.)

该程序是对飞行器的航迹进行模拟。包括3个文件，主程序是fangzhen.m，可以反映出飞行器高度、速度、攻角等参数对飞行器航迹的有效(The program is a simulated aircraft track. Includes three files, the main program is fangzhen.m, can reflect the aircraft altitude, speed, angle of attack of the aircraft trajectory parameters are valid)

通过将TLE参数信息的录入，通过SGP4模型求出位置参数(SGP4 MODEL)

jacobi奇异值分解，matlab 用于利用矩阵填充和矩阵回复解决图像处理问题(the jacobi singular value decomposition)

利用迭代法实现图像阈值分割，简单好用，自带matlab图像直接运行(terative method to achieve image segmentation, easy to use, comes directly run matlab image)
