1 引言
小波分析是近十多年来迅速发展起来的新兴学科和信号分析理论，是继傅里叶分析方法之后的重
大突变。它具有时域局部化和频域局部化的优点，而且高频端的时间间隔小（有着高的时间分辨率），
低频端的时间间隔大（有着高的频率分辨率），这与人的视觉机制由粗到细的认识过程相一致，固而有
“数学显微镜”之称，是进行信号处理和分析的有效工具。特别是其多分辨率分析理论及其快速算法

Description: 这是一个基于M/M/S类型的排队论仿真程序。M/M/S表示到达时间为负指数分布，服务时间为负指数分布，服务设备数量为S个的排队系统。
（1）到达模式：严格意义上讲是一个接着一个到达，而且到达时间间隔服从参数为mean_arr的负指数分布；
（2）服务模式：服务台的数量为server_num,且每个服务台服务一个顾客的服务时间服从参数为mean_serv的负指数分布；
（3）排队规则：满足先进先服务，服务快的先离开的规则。
-This is a based on the M / M / S types of queuing theory simulation program. M / M / S said time of arrival of the negative exponential distribution and service time for the negative exponential distribution, service equipment for the number of S-queuing system. (1) mode of arrival : a strict sense is a one followed arrived, but the inter-arrival time parameters mean_arr obey the negative exponential distribution; (2) mode : The number of help desk server_num. with each help desk services a customer service parameters mean_serv obey the negative exponential distribution; (3) queuing rules : first meet advanced services, the first to leave fast rules.

Description: This book aims to give a general overview of the theoretical foundations of
learning theory. It is not the rst to do so.Yet we wish to emphasize a viewpoint
that has drawn little attention in other expositions, namely, that of approximation
theory. This emphasis fullls two purposes. First, we believe it provides a
balanced view of the subject. Second, we expect to attract mathematicians
working on related elds who nd the problems raised in learning theory close
to their interests.

Description: 矩阵是高等代数学中的常见工具，也常见于统计分析等应用数学学科中。[2] 在物理学中，矩阵于电路学、力学、光学和量子物理中都有应用；计算机科学中，三维动画制作也需要用到矩阵。(Matrix is a common tool in higher algebra, and it is also common in Applied Mathematics, such as statistical analysis. [2] is applied in physics, including matrix in circuit, mechanics, optics and quantum physics. In computer science, three-dimensional animation is also required to use matrix. The operation of matrix is an important problem in the field of numerical analysis. The decomposition of a matrix into a combination of simple matrices can simplify the operation of a matrix in both theoretical and practical applications. For some widely used and special forms of matrix, such as sparse matrix and quasi diagonal matrix, there are specific fast arithmetic algorithms. For the development and application of matrix related theory)
