判断系统上升时间，峰值时间，超调量和调整时间。《自动控制》清华出版社的课后编程题目。(Determine the system rise time, peak time, overshoot and time to adjust. )

利用自相关函数估计基音周期，函数jiyinzhouqi，输入参数是分析语音文件名和帧移，帧移在5~10ms(function jiyinzhouqi is used for estimate the period of fundamental tone.)

This is predictive simulation file. It contations too many mdl files. and it has predictive+802.11a simulink. Thank you

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.)
