用于计算离散信号的很不错的matlab样本熵程序(Very good for computing discrete signal matlab sample entropy program)

说明：  可实现对多个因素进行关联分析，选取关联度大的数据，排除关联度小的，从而降低实验误差。(It can realize the correlation analysis of multiple factors, select the data with large correlation, and exclude the data with small correlation, so as to reduce the experimental error.)

Gaussian Correction for Gravimetry processing in matlab

频谱分析，用于对等时间间距的序列进行频谱分析(spectrum analysis, for the time interval, such as the sequence spectrum analysis)

this is an example model for IEEE 34 bus system

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

vmd分解程序，修改版，可以用于处理实测振动信号。(vmd decomposition process, a modified version can be used for processing the measured vibration signal.)

说明：  OFDM的仿真，这种技术wimax已经采用，未来的4G肯定也是基于这种技术。附件是源代码，仅供大家参考！ (OFDM simulation, WiMAX technology has been adopted as the future 4G is definitely based on the technology. The annex to the source code, only your reference!)
