在心电信号中混入50HZ工频噪声，并设计自适应滤波器消除消除工频噪声。程序附有详细文字解释，可运行。(In the ECG signal mixed with 50HZ frequency noise, and design of adaptive filter to eliminate the elimination of power frequency noise. The program is accompanied by a detailed text explanation, can run.)

LSSVM classify最小支持向量机分类程序(LSSVM classify)

利用形态学方法，给ECG信号去基线漂移。基线漂移对心电影响很大。利用形态学上的腐蚀和膨胀，可以处理，但缺点是呈阶梯状，对原始信号有影响，这个是自己编的，未用matlab上的函数。(Morphological method to the ECG signal to baseline drift. Baseline drift on the ECG. Morphological erosion and dilation can handle, but the drawback is that the ladder-like effect on the original signal, this is their own series of unused matlab function.)

The pricing model for the Binomial tree model, for the up and in barrier call option
