EM算法代码

说明：  this is new approach for fuel cell control.it is really helpfull.

在齿轮箱故障诊断中，需要对故障信号进行特征提取，本程序是齿轮箱特征提取源代码。(Gearbox fault diagnosis, the need for fault signal feature extraction, the procedure is to extract the source code gearbox features.)

任务具体的技术描述，如： 学号指纹生成器的核心是根据组员学号的输入，生成对应的操作符，对组长学号进行迭代操作。 4个七段码作为组员学号的输入显示，和每次运算结果的输出显示； 2个开关状态 sw[3:0]作为组员数据输入 4个按键分配 btn[1]作为读按钮，用于读入组员学号数据，btn[0]为操作控制按钮，按一下对应一次学号操作； (Description of specific technical tasks, such as: student number generator is the core of the fingerprint according to members of input student ID to generate the corresponding operator, student number on the head of the iterative operation. 4 seven-segment code number as the members learn the input display, and the output shows the results of each operation two switching state sw [3:0] as a data input four key members assigned btn [1] as read button student number for members to read the data, btn [0] for the operation control button, click the corresponding operation of a student number )

说明：  利用自相关函数进行数据同步，解决了盲同步不准确的情况(use of the correlation function for data synchronization, a blind solution is not accurate synchronization of)

The PSNR is most commonly used as a measure of quality of reconstruction of lossy compression codecs (e.g., for image compression). The signal in this case is the original data, and the noise is the error introduced by compression

使用前请先将信号转换到时频域，最后将信号从时频域转换到时域(please transform the signal into time-frequency domain before using)

Compress an decomprres DCT=Domain Transform Coding for image.

介绍了matlab的命令大全，以及相关的matlab的应用(Introduced the matlab command Daquan, and related applications matlab)

说明：  极限学习机是一种神经网络仿真，比BP,SWM学习速度更快，参数设置更容易(Extreme Learning Machine is a kind of neural network simulation, compared with BP, SWM learning faster, easier to set parameters)

matlab编写的实用程序100个例子 非常适合初学者学习 可以省许多时间(Matlab prepared by the 100 examples of the utility is ideal for beginners to learn can save a lot of time)
