用vs2013写的霍夫曼编码程序，可将.txt中的英文字符串（包括各种字符如：逗号）编码后输出到一个.txt中，并且可输出构建的霍夫曼树,保存编码方式。(Huffman coding using vs2013 to write programs in English can be txt string (including a variety of characters such as: the comma). Encoded output to a txt, and can output to build Huffman tree, save the encoding. .)

德国低干扰谱，以及公路C级路面的路面不平度的c++实现。一些相关的资料，便于初学者理解。(German low interference spectrum, as well as C-level road highway pavement roughness achieved. Some relevant information, easy for beginners to understand.)

一本介绍aml编程设计的书籍.比较基础,实用.(aml introduced a program designed books. Basis for comparison and practical.)

说明：  利用C_Builder与Matlab实现实时数据的获取与处理(Matlab using C_Builder and real-time data acquisition and processing)

1D Ising ising1(n,m,b,p) n - length of domain, a positive integer m - number of iterations, a positive integer b - coupling parameter / temperature, a positive scalar b = 0 -> Very high temp / low coupling b > 1 -> Very low temp / high coupling( 1D Ising ising1 (n, m, b, p) n- length of domain, a positive integer m- number of iterations, a positive integer b- coupling parameter/temperature, a positive scalar b = 0-> Very high temp/low coupling b> 1-> Very low temp/high coupling)

说明：  遗传算法的源代码。MATLAB下支持，省得编代码了(Genetic algorithm source code. MATLAB to support clinics to save compiled code of the)
