全自动GM模型代码，能自动判断是否适合灰色预测，并给出残差预测模型代码(Fully automatic GM model code can automatically judge whether it is suitable for grey prediction and give residual prediction model code.)

此文件为四种空间DOA估计的MATLAB程序，包括：MUSIC, ROOTMUSIC，ESPRIT和MVDR四种方法，并带有相应的仿真图，便于比较其优缺点,很有用哦(MATLAB for DOA estimate : MUSIC, ROOTMUSI,ESPRIT and MVDR,the coresponding figures are acompanied to compare the advantages and disadwantages,they are useful)

说明：  用matlab打开即可，可以绘制功率谱的函数(using Matlab can be opened, the power spectral mapping function)

此仿真的原理基于压缩感知理论，以LFM为采集信号，测量矩阵使用的是伯努利矩阵，恢复算法采用的是OMP算法，恢复效果不错，想学习压缩感知方面知识的可以下载仿真使用！ (The principle of the simulation based on compressed sensing theory, collection for LFM signal, measure matrix using Bernoulli matrix, recovery algorithm USES is OMP algorithms, recovery effect is good, want to learn simulation using compression perceptual knowledge can download!)

从给定的一系列点找出最佳拟合椭圆,如果无法找出拟合椭圆，将返回一个空矩阵(fit_ellipse- finds the best fit to an ellipse for the given set of points.)
