说明：  实用C++计算一篇英文文本的信息熵 1、 读取文档，统计英文字母及空格出现的次数； (将小写字母转为大写字母进行计数) 2、 求概率分布P(X)； 3、 根据定义求信息熵。(Computing the information entropy of an English text with C + + 1. Read the document and count the number of English letters and spaces; (convert lowercase letters to uppercase letters for counting) 2. Calculate the probability distribution P (x); 3. According to the definition of entropy.)

一个用csharp写的计算器程序，内容较简单，适合初学者(using csharp write calculator,easy for first study!!! )

使用高阶累积量对MPSK信号进行调制识别，微分方程组数值解方法，分数阶傅里叶变换计算方面。( Using high-order cumulants of MPSK signal modulation recognition, Numerical solution of differential equations method, Fractional Fourier transform computing.)

编写C程序，随机给出n*n的邻接矩阵，并打印输出邻接矩阵，以及有向图的边的个数，每个顶点的度，并判断该图中是否存在Euler回路： （1）如果为n阶，则随机产生一个n*n的邻接矩阵； （2）输出邻接矩阵，边的个数，每个顶点的度以及图中是否存在Euler回路。 这个题目涉及到了两个主要的知识点，一个是数据结构中的有向图的邻接矩阵的创建，还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)
