说明：  自己编的 利用隐式马尔科夫过程进行目标状态估计(Using implicit markov process to estimate target state )

波达方向估计一直是信号处理的经典问题，本文利用盲子空间思想，新颖独特。(DOA Estimation of signal processing has been a classical problem, we use the blind subspace thinking, innovative and unique.)

无限大藏储试井分析图版，分析无因次压力变化以及导数变换(Infinite reservoir in well test analysis Plate)

MATLAB控制系统仿真与实例详解（附书光盘）包括该书的所有参考程序，简单易懂(MATLAB simulation and control system for example explanation () CD attached books including the book of all the reference program, easy to understand )

This code is very useful to detect key-points, extract features those key-points. This code is useful to detect SIFT key-points

关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

dc-dc buck电路，仿真效果较好，偏差控制的很小，pi效果不错(DC-DC buck circuit, simulation effect is good, deviation control is very small, PI effect is good.)
