MATLAB命令大全，常用示例。对使用MATLAB的人，有很大帮助。(MATLAB all command.example. etc.)

Adaptive Communication Environment

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.)

采用MATLAB自身的三电平PWM模块，搭建三电平逆变器，输出电流波形正弦度非常好。(Using MATLAB s own three-level PWM module, to build three-level inverter, sine wave output current is very good.)

说明：  matlab状态方程的设计和一个自己编的小小的filter文件请指教！！1(Matlab equation of state of their own design and a series of small filter paper please enlighten! ! 1)

Quadratic programming

说明：  用割线法求函数极值，能求出初始点附近极值点，包括极大值和极小值(Secant extremal function, can be obtained in the vicinity of the initial point of extreme points, including the maximum and minimum values)

说明：  数据快照的特征提取，获得基模态、特征值和模态系数，以及数据的后处理。(Feature extraction of data snapshot, obtaining basic modes, eigenvalues and modal coefficients, and post-processing of data.)

粒子群算法的标准程序,非常易懂，适合初学者。(The standard programme of PSO)

matlab编程，通过设计训练一个人工神经网络来达到其对一个4传感器实时检测输出结果融合判断的模拟，文中涉及人工圣经网络和多传感器融合两们学科的基本知识。(matlab programming, through the design of training an artificial neural network to achieve its real-time detection of a 4-sensor integration to determine the output of the simulation, the text of the Bible involved in the artificial network and multi-sensor fusion of two disciplines have a basic knowledge.)
