针对医疗中的心电信号，利用奇异性检测的方法检测R波的位置,并给出模极大曲线(against the medical ECG, the use of the singular method of detection of R-wave detection of the location, and gives modulus maxima curve)

说明：  meanshift跟踪算法的实现，主要是利用metlab来完成的，效果还不错(mean shift tracking algorism)

pfc boost converter single phase

利用分步傅立叶积分法，计算了光纤中色散与SPM效应(Step-by-step use of Fourier integral method, the calculation of the fiber dispersion and SPM.)

该模型实在simulink下建立的燃料电池氢气输出模型，可以借鉴或者直接使用(fuel cell H2 model )

这是一个债券交易策略。由2条交叉线产生交易信号。( This MATLAB function implements a simple band trading strategy. A band consists of two lines that form the upper and lower boundaries of the band. The upper and lower boundaries are used to to enter and exit trades. For example, if prices fall below the lower boundary a buy signal is generated. )
