这次上传的代码是关于K-means clusters的代码，希望能对大家有用。(The uploaded code is about K-means clusters.I hope it can be a help to everyone.)

生命系统建模——血液血环系统的建模，能够对多种心血管疾病情形进行模拟。(Life System Modeling- Modeling blood blood ring system, it is possible to simulate a variety of cardiovascular disease situations.)

使用阈值法对脉搏信号的峰值进行提取，并且通过提取信号的峰值求脉搏信号的周期，并且简单判断脉搏信号的峰值是否可用。(Useing Threshold to extrack the peak of the pulse signal extraction, and determine the peak of the pulse signal whether is not available.)

可以用FFT频谱对脑电信号进行提取。我们可以利用提取出的各个波段脑电信号，来诊断一些脑部疾病或者对大脑组织的电活动及大脑的功能状态进行分析。 1.将实验测得的脑电数据文件转换为文本文件(已经过50Hz陷波)， 获得在Matlab 平台上可直接使用的脑电信号数据，即0661.txt。 2.在Matlab中导入数据，并提取Fp1通道的脑电信号，通过FFT变换对α，β，θ，δ波段进行提取，并做FFT逆变换变到时域。 3.计算各个波段的功率谱。(FFT spectrum can be extracted on EEG. We can use the extracted EEG each band to diagnose some brain disorders or brain tissue on the brain' s electrical activity and functional status were analyzed. One would experimentally measured EEG data file into a text file (has been 50Hz notch), obtained in Matlab platform can be used directly EEG data, that 0661.txt. (2) import data in Matlab and extract Fp1 channel EEG by FFT transform α, β, θ, δ bands were extracted, and do FFT inverse transform variable to the time domain. 3 calculate the power spectrum of each band.)

说明：  作者使用matlab程序开发了脑电图信号接口程序，并利用小波分解对脑电信号节律提取。(By using the matlab program development of EEG signal interface program, and the use of wavelet decomposition of the EEG rhythm extraction.)
