在时间序列分析中自动完成数据的导入、分析与导出(In time series analysis is done automatically import data, analysis and export)

基于BUCK电路的光伏发电扰动法MPPT跟踪(PV perturbation method based BUCK circuit MPPT )

<精通MATLAB>根据这本书写的相应的运筹学里的源代码，都是最基本的算法，没有进行改进(<Proficient in MATLAB> According to this writing tacticians in the corresponding source code, are the most basic algorithm, no improvements)

没有用工具箱的DCT变换，采用不同压缩率，能够加深对DCT变换的了解。(Do not use toolbox of DCT, using different compression ratios, to deepen understanding of the DCT transform.)

说明：  OFDM仿真程序，信道估计采用LS,MMSE,LMMSE,DCT等方法，做了个比较，ofdm那个是主程序(OFDM simulation program, channel estimation using LS, MMSE, LMMSE, DCT and other methods, made a comparison, OFDM that is the main program)
