说明：  本程序为块匹配算法的快速搜索策略，菱形搜索法，也叫钻石搜索法(This program is fast block-matching algorithm search strategy, diamond search, also called the diamond search method)

说明：  本程序主要是用Matlab进行编写的关于bermark函数的遗传优化算法(matlab)

永磁同步电动机的开环控制的matlab/simulink仿真。供大家学习。(Permanent magnet synchronous motor open-loop control matlab/simulink simulation. For everyone to learn.)

先对语音信号进行采集、播放，分析其频谱，对该信号源添加噪声，再播放音频并分析频谱，然后分别通过IIR低通、带通滤波器和FIR低通、带通滤波器，分别播放音频和得到滤波后的频谱。(Firstly， voice signal acquisition, play, analyze its spectrum to add noise to the signal source, and then play the audio spectrum analysis, and then were by IIR low-pass, band-pass filter and FIR low-pass, band-pass filters, respectively, play audio and get the spectrum after filtering.)

LMS_Newton算法，应用于自适应滤波(LMS_Newton algorithm used in adaptive filtering)

对于Matlab中simulink模块仿真进行了详尽的说明 主要用途集中在控制系统仿真上(This is a introduction of simulation of dynamic system based on the simulink module. This article focus on the control system.)
