谱分解（Spectral decomposition），是将矩阵分解为由其特征值和特征向量表示的矩阵之积的方法。(Spectral Decomposition , is the product of the matrix into the matrix method by eigenvalues and vector representation.)

EMD/HHT是一种处理非线性非稳态信号的经典算法，自98年提出以来已经获得广泛的使用，作者huang曾经因次获得NASA的最高奖。(EMD/HHT is a deal with the nonlinear non-stationary signals classical algorithm, since 98 has been raised since the widespread use huang had dimensionless author was NASA's highest award.)

matlab动态波浪图并带有功能键，点击可调节波浪的跳动快慢(Dynamic wave graph MATLAB and a function key, click on the wave speed can be adjusted. )

Using Simulink Simulink is a software package for modeling, simulating, and analyzing dynamical systems. It supports linear and nonlinear systems, modeled in continuous time, sampled time, or a hybrid of the two. Systems can also be multirate, i.e., have different parts that are sampled or updated at different rates
