说明：  太阳光聚焦光线偏移的一个小程序，方便大家学习与应用。(Focus sunlight light offset a small program to facilitate learning and application.)

用matlab中的SIMULINK实现3路信号采样、时分复用传输和接收分路过程的仿真模型(3-way signal sampling, time division multiplexing transmission and reception process simulation model shunt)

matlab code for averaging data time series

免疫粒子群混合优化算法整定PID，该方法将免疫算法中的基于浓度的抗体繁殖策略 与粒子群优化算法相结合。对浓度低的粒子进行促进，对浓度高的粒子进行抑制，因而保持了粒子的多样性，克服了PSO 算法易于陷入局部最优点的缺点，寻优速度快。(PID paramaters optimization by AIPSO)

matlab源程序，用于计算数值微分，里面有很多的有关数值微分的matlab程序。(matlab source code used to calculate the numerical differentiation, which have a lot of the numerical differentiation of the matlab program.)

形态学滤波器 matlab程序，主要用于特征提起、信号处理(Morphological filter matlab program, mainly for the characteristic lift, signal processing)

matlab下面一个很经典的例子，适合刚入门的人 学习(dddddddddddddddd)

说明：  Belief Propagation (BP) Implementations gabp.m, run_gabp.m => Gaussian BP - parallel version asynch_GBP.m => Gaussian BP - serial version sparse_gabp.m, run_sparse_gabp.m => Gaussian BP - sparse version, optimized, tested on sparse matrices gabpms.ms, run_gabpms.m => Quadratic Min-Sum algorithm - Moallemi and Van-Roy

说明：  数据进行预处理，时域、频域等特征分析以及求取心率指标，并设计GUI界面(Data preprocessing, time-domain, frequency-domain characteristic analysis and heart rate index calculation, and GUI interface design)

matlab分别实现低通，带通，高通滤波器的程序(Filter-lowpass,bandpass,highpass. matlab )
