BP-Example

A Quadrotor simulation that is performed in MATLAB and SIMULINK

The MATLAB DMTTEQ Toolbox is a collection of MATLAB functions to design and test the following time domain equalizer design methods

双基地声纳定位精度GDOP与目标方位的关系，目标方位为与过基线中点法线的夹角。(Bistatic sonar positioning accuracy GDOP relationship with the target position, the target azimuth angle between the baseline and over the midpoint of normals.)

利用matlab自带的BP神经网络工具箱对duffing混沌背景模型进行相空间重构与预测，程序中已经给出duffing函数，主函数中也给出了主要注释，方便大家学习交流。(BP' s own use matlab neural network toolbox for duffing chaotic background model and prediction of phase space reconstruction, the program has been given duffing function, the main function also gives the main note, we facilitate learning exchanges.)

如何计算矩阵数据的协方差矩阵。还有在什么情况下只能计算均值、方差，而不能计算协方差，什么情下，只能计算协方差，但不能计算协方差矩阵。(How to calculate the matrix data covariance matrix. And under what circumstances can only calculation mean, variance, and not calculation covariance, what feeling, can only calculation covariance, but not calculation covariance matrix.)

reduces cycles in bipartite graph

This code get the path of images and extract features of these images , then use the NN tool for training

audio signal processing and recognition,是一本台湾张智星教授所写的关于语音处理的书籍，网上有另一个版本书名叫《audio processing》，和这个有点区别，两个结合看效果会更好！(audio signal processing and recognition, is a book written by Professor Zhang Zhixing Taiwan books on speech processing, there is another version of the online book called "audio processing", and this little difference, the two combined to see better results!)

说明：  Hilbert变换工具箱，可用于单分量信号的解调，求取瞬时幅值和瞬时频率(Hilbert transform toolbox, which can be used for demodulation of single component signals, to calculate instantaneous amplitude and instantaneous frequency)

this program is very useful for the comparison of lms and recursive least square method for beamforming in the application of wireless communication
