無監督分類方法，可以對一堆數值自動的歸類(Unsupervised classification methods, can be a pile of automatic classification of numerical)

Function developed in MATLAB for the creation of a RGB Cube

说明：  用Matlab/simulink所实现的bpsk性能仿真系统，信道为AWGN信道。运行后，可以看到经过bpsk以后信噪比的增益。(using Matlab/Simulink BPSK achieved by the performance simulation system for the channel AWGN. After the operation, we can see the future through BPSK SNR gain.)

说明：  数字信号图象处理,对数字图象进行滤波和中值化(digital signal image processing, digital image filtering and the value of)

本例研究利用Matlab工具箱的BP网络仿真某系统故障的预测,假设3个故障的样本分别为(1 1 0), (0 1 1)(1 0 1), 3个故障分别编码为(1 0), (0 1), (1 1),下面利用BP工具函数设计网络,用自适应学习率算法进行BP的设计、训练和仿真。(cases using the Matlab toolbox BP network simulation of a system fault forecast Assuming three fault samples were (1 1 0), (0 1 1) (1 0 1) three failures were coded as (1 0), (0), (1), below BP network design tool function, Adaptive learning rate BP algorithm design, simulation and training.)

calculate the approximate entropy of heart rate varibility

matlab实现信号分类，根据信号的相关性，获取信号类别，自动进行信号分类(matlab realize signal classification, in accordance with the correlation signal to obtain the signal type, automatic signal classification)

说明：  变异的粒子群算法，具有很好的稳定性，不会进入局部收敛。遍历速度大大提高。(Variation of the particle swarm algorithm has good stability, will not enter the local convergence. Traverse speed greatly improved.)

正交频分复用(OFDM)技术及其MATLAB模拟(orthogonal frequency division multiplexing (OFDM) technology and its MATLAB simulation)

从人的语音提取特征值的一种方法，lcp可能有些旧，但是还是不错的一种方法。(Extracted from the voice of a method of eigenvalue, lcp may be old, but still quite a way.)
