众所周知，欧拉角和四元数是存在对应关系的。后者用于导航等时不存在死区现象，而且，精度高，计算简单。(known, the Euler angles and quaternion is a correlation between them. Navigation for the latter did not exist at the Dead phenomenon, and with high accuracy, is simple.)

Linear array acoustic phase delay beamformer including four plots: windowless, and Chebyshev, Gaussian and Tukey windows.

This toolbox implements an energy-based segmentation algorithm that uses finite-difference based level set evolution.

降维工具箱，有PCA，LDA等等比较全面，里面有说明。(Dimensionality reduction toolbox, PCA, LDA, and so a more comprehensive, there are instructions.)

通信系统的4qam盲均衡程序，希望对大家有点帮助(Communication systems 4qam equalization program, we hope to be helpful)

学习线性分类器，可以自动识别两类数据点，数据点可以有交叉域，或者没有，共使用了三种方法。(Learning the self-learning process of linear classifier, and then design a linear two-class classifier and do some research based on the feature of linear classifier.)

介绍Matlab工具箱的书籍，提供了能够打开的阅读器。(Matlab Toolbox to introduce the books, providing the reader to open.)

说明：  BP网络是通过输入层到输出层的计算来完成的。多于一层的隐含层虽然能在速度上提高网络的训练,但是在实际应用中需要较多的训练时间,而训练速度可以用增加隐含层节点个数来实现,因此在应用BP神经网络进行预测时,选取只有一个隐含层的三层BP神经网络就足够了。(The BP network is completed through the calculation of the input layer to the output layer. Although the hidden layer of more than one layer can improve the training of network in speed, more training time is needed in practical application, and the training speed can be realized by increasing the number of hidden layer nodes. Therefore, when the BP neural network is used to predict, the three layer BP neural network with only one hidden layer is sufficient.)

MATLAB的应用可以遍及通信，信号处理等等，而MATLAB相关函数、命令则更是重要无比，掌握这些命令，对于我们学好MATLAB大有裨益。(MATLAB applications can throughout the communication, signal processing, etc., while the correlation function of MATLAB, the command is even more extremely important to master these commands great benefit for us to learn MATLAB.)
