顺便附上几张仿真图 这是状态图 要注意的是：必须把系统状态和kalman滤波器内部预测的状态分开(Incidentally, several simulation map attached to this is the state diagram should be noted that: must be the system state and kalman filter to separate the state of internal forecasts)

说明：  matlab说明，各种各样的公式符号说明(matlab shows a variety of formulas symbol description)

该例程是基于人耳掩蔽效应的语音增强算法的MATLAB实现。压缩包中附带参考文献（基于人耳掩蔽效应的谱减算法的研究与实现）、测试所使用的音频信号、以及段信噪比计算函数。源代码中MaskingSub.m（源代码主要部分）及Main.m为本人所写，其余均来自程序员联合开发网。运行环境MATLAB R2009b(Key words:masking property, spectral subtraction algorithm)

排序问题，几个老师对多名学生打分，然后对学生进行排序(Scheduling problem, more than a few teachers of students scoring, and then sort the students)

Exact Recovery of Sparsely-Used Dictionaries

深度学习的一些工具包和一些例程，有关于BP神经网络，卷积神经网络等。用于熟悉相关算法基本够用。比较适合想了解此类内容的初学者。(Some Tools of deep learning. Eg:NN,CNN,BP and so on. It s pretty well to student.)
