说明：  建立关联程序的例子。本程序演示把 .bar 文件与 NotePad 建立关联(establish procedures related examples. The demonstration put procedures. Bar documents associated with the establishment of NotePad)

说明：  有限差分法数值模拟弹性波动方程，使用matlab编写的。(Finite difference method numerical simulation of elastic wave equation, using matlab prepared.)

模拟退火算法的MATLAB的实现。欢迎大家下载。(MATLAB simulated annealing implementation. Welcome to download.)

这个我用matlab写的一个简单孤立词语音识别的程序，其中同过预处理，ＭＦＣＣ提取，和ＤＴＷ算法的比较，如果大家愿意，还可以用这个和ＬＡＢＶＩＥＷ联合编程(Matlab write this I used a simple isolated word speech recognition procedures, which had the same pretreatment, MFCC extraction, and the DTW algorithm, if everyone is willing, but also can use this joint programming and LABVIEW)

输入信号五个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，得到识别出的信号类别，本例为2PSK, 4PSK, GMSK, OQPSK, pi/4DQSK中的一个，还可以看Art网络的扩展性。(input signal instantaneous information on five characteristics : In the center is one of the instantaneous rate of the power spectral density of the maximum, is a center to the absolute value of the instantaneous rate of the standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component absolute standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component standard deviation, In the center is one of the non-weak signal of the absolute value of the instantaneous frequency standard deviation, the identification of signal type, The cases of two PSK, 4PSK, GMSK, OQPSK, pi/4DQSK of one, Art can be viewed network scalability.)

Simple Function Approximation

这是基于滑膜观测器的永磁同步电机的无速度传感器的的模型，改模型能够切换到滑膜控制的速度估计。(This is a permanent magnet synchronous motor based on synovial observer without speed sensor model, change model can switch to the synovial control speed estimation)

说明：  简单的DMC以及MPC控制代码和说明都有，不错的学习参考(Simple DMC and MPC control code and instructions are available, good learning reference)

对于初学者很有用的EMD程序。供大家参考。(EMD useful for the beginner process. For your reference.)

自己做的： （一）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅰ型低通数字滤波器，其采样频率Fs =8KHz，1DB通带边界频率为fp=2KHz。 （二）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅱ型高通数字滤波器，其采样频率Fs =16KHz，阻带边界频率为fst =4KHz(matlab gui)
