Rossler混沌系统加入控制器后，在控制器作用下在有限时间内仍然达到了镇定(Rossler chaotic system to join the controller after the controller under a limited period of time still to reach a calm)

This is code for QRS peak detection in ECG signal. An ECG signal is generated and it is been filtered. The output is Filtered output.

本程序需要用到MATLAB遗传算法工具箱，但是遗传算法工具箱有很多种，这里使用GEATbx工具箱，该工具箱是由英国Sheffield大学开发。(This program requires MATLAB genetic algorithm toolbox, but there are many genetic algorithm toolbox used here GEATbx toolkit, which was developed by the University of Sheffield, UK.)

常见压缩感知算法汇总，L1,OMP,GP(Common used compressed sensing algorithm summary, L1, OMP, GP)

OFDM系统仿真，信号采用卷积编码和交织技术、采用16-QAM和QPSK两种调制方式，干扰分别采用多径衰落和瑞利衰落两种。(OFDM system simulation, signal the use of convolutional coding and intertwined technology, using 16-QAM and QPSK modulation in two ways, interference were used to multipath fading and Rayleigh fading two.)

说明：  用中心差分实现一维小波变换，可自行作改进(with center differential to achieve a peacekeeping wavelet transform, the discretion to make improvements)

股票指数模拟为几何布朗运动，GBM。 参数有五个： s0，dt（time step），均值，标准差，到期时间T； 利用子函数进行10万条轨道的monte carlo 模拟到期日（3个月）的指数点数，从而估计在买入信号出现后，3个月后的损益情况，主要用来估算VAR (Financial risk analysis on Matlab monte carlo simulation, stock index simulation for geometric Brownian motion, GBM. )
