libc 详细说明了C库里代码的实现过程，里边有详细的注释(detailed description of the C library libc code implementation process, detailed notes inside)

各种经典PID的MATLAB程序，主要涉及温度控制，压力控制，液位控制等(All kinds of classic PID MATLAB procedures, mainly related to the temperature control, pressure control, level control, etc )

说明：  给定n种物品和一个背包,物品i的重量是Wi,价值是vi,被包容量是C,应该如何选择装入被包的物品,使得装入背包中物品的总价值最大?对于每种物品i,只有两种选择,装入或者不装入. 输入:第一行两个正整数n(物品数)和C(容量) 第二行n个正整数n,表示物品价值 第三行n个正整数n,表示物品重量 输出:第一行表示总价值 第二行n个数(0/1),0表示物品不装入,1表示装入 例如, 输入: 5 10 6 3 5 4 6 2 2 6 5 4 输出 15 1 1 0 0 1 (Species of a given n items and a backpack, the weight of item i is Wi, the value of vi, was packet capacity is C, should be how to choose a package of items to be loaded, the backpack load in the largest total value of goods? For each item i, there are only two options, loaded or not loaded. Input: the first line of the two positive integer n (the number of items) and C (capacity) of the second line of n positive integer n, that the value of the third line of n positive integer n, that the weight of output: the total value of the first line of the second line, said n number of (0/1), 0 that the items do not load, that load 1 for example, enter: 5,106,354,622 6 5 4 output 15 1 1 0 0 1)

一个很好的通用虚拟示波器，基于vc编写的，非常好用(A good general purpose virtual oscilloscope, based on the vc prepared, very easy to use)

自己编写的matlab简单计算，用于计算矩阵的加减乘与求逆，特征行列式等(I have written matlab simple calculation used to calculate the matrix addition and subtraction, multiplication and inversion, characteristic determinant, etc.)

Default constructor MyString::MyString() { m_szString = NULL m_aSize = 0 cout << "Default constructor from my sting " }

水文时间序列 每旬的极端事件计算，该指标用于混沌计算前期处理(Hydrologic time series of extreme events is calculated every ten days, the index is used to calculate the pre-treatment of Chaos)

形态学的膨胀，腐蚀，细化的MATLAB的源代码，对初学者有用(Morphological expansion, corrosion, thinning of MATLAB source code, useful for beginners)

I have often found that user input edit boxes on a dialog require much more than the capabilities provided by the basic CEdit control. A common problem I have encountered is the need for an edit control that restricts the characters that can be entered into the box in some manner. Some types of restrictions would include confining input to a specific set if legal characters, excluding characters in an illegal set, limiting text to a maximum length and providing for fixed length strings that may be padded to the right with spaces if they are too short.
