lmd 采用滑动平均处理，调整过，可以直接运行出图。(lmd hua dong pingjun)

matlab training for all

说明：  Matlab从入门到精通中所有的源程序。(Matlab from entry to master all of the source.)

说明：  微弱信号的提取检测和分析 用matlab实现的源代码 首先计算输入信号的均值、均方值、方差、频谱及功率谱密度，确定输入信号中包含着有用信号。然后提取有用信号，并要求计算提取信号的均值、均方值、方差、概率密度、频谱及功率谱密度，并画出曲线(The extraction of weak signal detection and analysis)

在Matlab/Simulink中对UniTire统一轮胎模型建模，仿真分析纵滑与侧偏的联合工况(In Matlab/Simulink modeling in unified tire UniTire, simulation analysis of longitudinal slip and yaw joint working conditions)

说明：  本程序用matlab编写，给出了特定参数下，光纤掺杂深度与阈值之间的关系(pumping threshold vs adoping density)
