希尔伯特黄变换的代码测试程序，其中主要执行test主程序(Hilbert-Huang Transform code testing procedures, which mainly perform test main program)

说明：  该仿真模型搭建了Buck-boost仿真模型，实现输入电压的变换(The Buck-boost simulation model is built to realize the input voltage conversion.)

Matlab设计FIR,IIR，应该很有帮助的吧(MatlabFIR,IIR is important)

局部均值分解(Local Mean Decomposition)，处理非线性非平稳信号的一个方法，LMD是依据信号本身的信息进行自适应分解(Local Mean Decomposition, a method for processing nonlinear non-stationary signals, LMD is adaptive decomposition based on the information of the signal itself.)

基于神经网络之中的BP算法的matlab仿真(Based on the BP neural network algorithm matlab simulation)

说明：   基本粒子群优化算法Matlab源程序 (Elementary particle swarm optimization algorithm Matlab source code)

说明：  学习阶段自己写的，语音信号去噪的matlab程序，希望大家给出批评指正意见。(Stages of learning to write their own, the speech signal denoising matlab program, hope that we are given the views of critics correction.)
