任意时间任意经纬度太阳方位角高度角计算程序(Latitude and longitude of the sun at any time of any azimuth elevation angle calculation program)

采用波束形成法，判断来波的方向，识别声源的位置(Using the beamforming method, to determine the direction of the wave, the position of the sound source identification)

自适应波束形成，天线方向图，幅相误差校准，相控阵天线(Adaptive beam forming, antenna pattern, amplitude and phase error calibration, phased array antenna)

说明：  本案例给出了振动信号的时域信号分析，fft分析，低通滤波分析和Hilbert包络分析代码，并将分析结果展现在一个图中进行对比。(This case gives the time domain signal analysis, FFT analysis, low-pass filter analysis and Hilbert envelope analysis code of vibration signal, and shows the analysis results in a figure for comparison.)

说明：  本程序用pca，kpca,svm,pls,fisher，贝叶斯实现cstr和csth过程的故障检诊断，诊断率为百分之九十九，故障识别率为百分之七十四(The program use pca, kpca, SVM, PLS, fisher, bayesian realize CSTR and CSTH process for diagnosis fault diagnosis rate is ninety-nine percent, and the fault recognition rate is seventy-four percent )

K-means++算法实现，加强了初始聚类点的选取（careful seeding）(K-means++ algorithm to enhance the selection of the initial clustering points (careful seeding))

说明：  《信号与系统》奥本海姆著，信号分析处理的经典教材，学小波分析必看的基础书(&quot Signals and Systems&quot Oppenheim a, signal analysis and processing of the classic textbooks, school books based on wavelet analysis a must-see)
