一个时滞系统的工具箱，可以求解线性，非线性时滞系统的状态响应，阶跃响应等(A time-delay systems toolbox, you can solve the linear, nonlinear time-delay system of state response, step response, etc.)

用蝙蝠算法（BA）对极限学习机（ELM）的输入权值和偏执进行进行优化，其诊断精度有明显提升。(With bat algorithm (BA) on Extreme Learning Machine (ELM) input weights and paranoia were optimized diagnostic accuracy has improved significantly.)

说明：  该系统为基于MATLAB平台的PCA的人脸识别系统，可识别ORL和YALE人脸库，方法实现统一，包括GUI界面。另外可二次开发成摄像头的实时人脸系统，识别出库外人脸，可做成门禁系统，考勤系统，打卡签到系统。实现登记出勤，报警等。 含论文，详细注释。(The system is a PCA face recognition system based on MATLAB platform. It can recognize ORL and yale face database. The method is unified, including GUI interface. In addition, it can be developed into a real-time face system of camera, which can recognize the face outside the warehouse, and can be made into access control system, attendance system, punch in system. Register attendance, alarm, etc. Including paper and detailed notes.)

介绍如何用matlab设计fir滤波器，很详细！！！！！！！！！！！！！！！！！(A great progress in the discipline of digital processing is the research on design method of digital filter. FIR digital filter plays a significant part in the processing of digital signal because it can realize linear phase so conveniently that the group delay doesn’t vary with frequency. In the modern electrical system, the FIR digital filter is applications for its good linear phase character.)

说明：  此为对于均匀阵列的MUSIC算法的源代码，希望对大家有用(this a uniform array for the MUSIC algorithm source code, we want to help!)

这是关于PCA主成分分析降维，文件夹里有.mat格式的数据文件，里面数据可供测试PCA降维使用。(This is about PCA principal component analysis dimension reduction, folder. Mat data file format, data available for test use PCA dimensionality reduction.)
