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.)

Simulation of Speech Enhancement using Spectral Subtraction

simulink下mdl的例子，用于帮助学习simulink(simulink under mdl example, be used to help learn simulink)

模拟退火算法matlab源程序，有应用例子(Simulated annealing algorithm matlab source, application examples...)

基于matlab的工具箱，应用模糊控制系统方法设计实现PID控制。(Based on Matlab toolbox, the application of fuzzy control system design method achieves the PID control.)
