说明：  脑电地形图matlab代码，包括电极位置文件和使用说明，麻雀虽小五脏俱全，下载后可直接使用(BEAM matlab code, including electrode position files and instructions for use, small but perfectly formed, the download can be used directly)

使用高斯混合模型（GMM)模拟模式识别的源代码(The use of Gaussian mixture model (GMM) Analog Pattern Recognition of the source code)

用matlab编写的遗传算法优化神经网络的经典程序(Prepared using matlab genetic algorithm optimization of the classical neural network program)

通过matlab仿真实现香浓限的逼近，并进行比较。(Matlab simulation of the Shannon limit approaching, and for comparison.)

自己编写的短时傅里叶变换（STFT）程序，短时傅里叶变换可以获得非平稳信号的时频图，主要原理是用滑窗截取一段信号，认为这一段时间内信号是平稳的，对其进行fft变换获得频谱(I have written a short time Fourier transform (STFT) program, short-time Fourier transform can be obtained non-stationary signal frequency diagram, the main principle is the interception of a signal with a sliding window that within this period of time the signal is stationary, access to spectrum fft transform them)

matlab 自动生成各种随机数的命令，希望对大家有所帮助(hehe ，it is very useful to us.I hope it can give everyone a help.)

用于计算MDL，最小描述距离。用于最小描述距离的计算，可以用于最优化过程(Used to calculate the MDL, Minimum Description distance. Used to describe the minimum distance calculations can be used to optimize the process)

MATLAB7.0基础教程，其中包括很多实例，对学习此软件很有帮助(MATLAB7.0 based tutorial, including many instances, this software is very helpful to the study)

该程序是用小波函数构建神经网络的源程序。用以分析心电信号、脑电信号等等。(that the procedure was constructed using wavelet neural network function of the source. For the analysis of ECG, EEG, and so on.)

this program is th simulink of lorenz map
