说明：  hht程序代码，小波变换，对比分量的功率谱密度函数图，找出最优小波(hht code, wavelet transform, as compared with the weight of the power spectral density function map to find the optimal wavelet)

fs = 8000 t = (0:1/fs:1). x1 = cos(2*pi*t*300) x2 = cos(2*pi*t*400) ha = phased.ULA( NumElements ,10, ElementSpacing ,1) ha.Element.FrequencyRange = [100e6 300e6] fc = 150e6 x = collectPlaneWave(ha,[x1 x2],[10 20 45 60] ,fc) rng default noise = 0.1/sqrt(2)*(randn(size(x))+1i*randn(size(x))) hdoa = phased.ESPRITEstimator( SensorArray ,ha,... OperatingFrequency ,fc) doas = step(hdoa,x+noise) az = broadside2az(sort(doas),[20 60])

在matlab中用delaunay函数实现三角剖分，在一个三角形区域内，实现简单的均匀的delaunay剖分。(In matlab function implementation using delaunay triangulation, in the area of ​ ​ a triangle, a simple uniform delaunay triangulation.)

图论工具箱，包括图论的相关操作，求最短路径，搜索，匹配，最大流，核数等(matlab graph toolbox)

里面包含m序列，gold序列的生成函数，还有自己编写的自相关函数的M文件。(Which contains m-sequence, the gold generating function of the sequence, as well as I have written the autocorrelation function M-file.)
