时频分析工具箱，作为补充MATLAB时频分析功能的源代码(Time-Frequency Analysis Toolbox as a supplementary function of time-frequency analysis MATLAB source code)

说明：  这是用matlab开发的pso工具箱，直观实用，对做这方面研究的人员很有用处(this is the development of PSO Matlab Toolbox, easy to use and the right to do this study of useful)

此源代码为基于Matlab的ofdm系统的仿真，全部的哦(The source code for ofdm systems based on Matlab simulation, all the oh)

performance description for codes in LTE applications

Space Vector PWM VSI Induction 3HP Motor Drive

说明：  通过粒子群优化算法优化PID参数，该算法对pid控制器参数进行整定，pso能够对参数实现优化，且有良好的收敛性。(PSO algorithm tuning PID parameters)

PID调节器结构简单、参数易于调整，当被控对象精确数学模型难以建立、系统的参数又经常发生变化时，应用PID控制技术，在线整定最为方便。 (PID adjustor simple structure, easy adjustable parameters, when the controlled object mathematical model is hard to build up, the parameters of the system and often changes, application of PID control technology, online setting the most convenient.)

OFDM仿真源代码，在通信系统中应用，调试通过(OFDM modulation system code)

ISODD Determines which elements of an array are odd numbers

说明：  使用matalab语言应用PLS算法对近红外光谱进行回归。(PLS algorithm is used to regress near infrared spectrum with MATALAB language)
