对信号进行小波变换，小波变换的分解与从构，以及一维静态离散小波分解-The signal wavelet transform, wavelet decomposition and from the structure, as well as the static one-dimensional discrete wavelet decomposition

该程序是依据matlab所编写的，基于对经验模态分解，及其改进算法的比较(The program is based on MATLAB. Based on empirical mode decomposition and comparison of its improved algorithms)

可能过MATLAB直接生成代码，以驱动步进电机。八拍(It is possible to generate code directly through MATLAB to drive stepper motors. Eight beat)

这是一个c语言的例子，是有关于加解密的程序，包含DES算法实现等(This is an example of C language, is about encryption and decryption procedures, including DES algorithm implementation, etc.)

　提出一种改进的禁忌搜索算法来求解背包问题。该算法基于禁忌搜索技术,并采用I&D策略,同时设计了两种针对局 部最优解的变异算子。改进后的算法能有效地弥补标准禁忌算法对初始解依赖的缺陷,同时也避免了搜索停滞的现象。通过对具 体实例和随机问题的测试,表明改进后的禁忌搜索算法有更好的性能。 关-An improved tabu search algorithm to solve knapsack problem. The algorithm is based on tabu search techniques, using I & D strategies, while designed for the local optimal solution of the two kinds of mutation operator. The improved algorithm can effectively compensate for the standard tabu search algorithm depends on the initial solution defect, but also to avoid the phenomenon of search stagnation. Through specific examples and random-question test, indicating that the improved tabu search algorithm has better performance. Guan
