说明：  its also about wireless sensor network

finite difference method有限差分法求波导的TM模式(finite difference method finite difference method for the TM waveguide mode)

china pub 出版的matlab书籍，扫描得很清楚。(matlab books, published by the china pub scan clearly.)

用于求解不可压ns方程的动量守恒计算方程的核心部分，采用了二维对称调用的技术。(Ns for solving incompressible equation of momentum conservation equation of the core part of the calculation, using a technique called two-dimensional symmetry.)

COFDM code in Matlab

说明：  MATLAB_stepper_motor_control.zip

some codes for calculate orbit definition

用MATLAB求平均路径长度，本程序很小(Using MATLAB and the average path length of the program is very small)

Trafic project with matlab about image processing

说明：  自编多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscaleSampleEntropy函数中的SampleEntropy也可以单独拎出来计算单个样本熵。(Multi scale sample entropy is used for a section of bearing fault data, which is easy to understand. SampleEntropy in the MultiscaleSampleEntropy function can also be picked up separately to calculate the entropy of a single sample.)
