this articl is about the LNMs,and it used the drude model to compute the materials property ,and is also a good example the tell FDTD applications!

神经网络PID自适应控制MATLAB程序集(the collect of the neural network PID adaptivly controls MATLAB procedure)

convolution program for entc engineers

时频分析工具，经典工具箱，包括短时傅里叶变换等实用函数 (Time-frequency analysis tools, classic toolbox, including the short time Fourier transform and other utility functions)

用牛顿拉夫逊法的极坐标形式计算电力系统潮流(Newton Raphson method polar form power flow calculation)

无线信道建模很复杂，不同场景下的模型差异较大，这是一本讲解无线信道建模方法的经典书籍配套的matlab例程(Channel modeling is complex models under different scenarios are quite different, which is a classic way to explain the channel modeling books matching matlab routines)

two-way-relay场景下，中继处理矩阵的设计，仿真分析了DPC-ZF及DPC-MMSE算法的性能要由于AF与ZF算法性能。(In the two-way-relay scenario,simulation show that both DPC-ZF and DPC-MMSE have a higher throughput and lower BER performance compared with the traditional AF algorithm and ZF algorithm.)

设置参数，创建输入信号,计算和显示比特误差率,绘制图形.(Set parameters, create the input signal, calculate and display bit error rate, draw graphics.)

This program alows you to add noise to a source and the remove the noise by filtering.

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.)
