DUNE (Distributed and Unified Numerics Environment)，分布和统一数值解环境，是一种求解偏微分方程的基于网格的方法（PDE）的模块化的工具箱。DUNE是所有这些体现了科学计算的概念从抽象的接口设置第一次。现代C + +编程技术使同样的概念非常不同的实现使用一个非常低的开销一个共同的接口。因此，DUNE确保在科学计算的效率，并支持高性能计算应用。(DUNE (Distributed and Unified Numerics Environment), distribution and unified numerical solution of the environment, is a solution of partial differential equations of the grid-based methods (PDE) of the modular toolbox. DUNE is that all these reflect the concept of scientific computing from the abstract interface settings for the first time. Modern C++ programming techniques to the same concept is very different implementations use a very low cost of a common interface. Therefore, DUNE ensure the efficiency of scientific computing, and supports high-performance computing applications.)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

蒙特卡洛模拟蒙特卡罗模拟因摩纳哥著名的赌场而得名。它能够帮助人们从数学上表述物理、化学、工程、经济学以及环境动力学中一些非常复杂的相互作用。 数学家们称这种表述为"模式"，而当一种模式足够精确时， 他能产生与实际操作中对同一条件相同的反应。但蒙特卡罗模拟有一个危险的缺陷: 如果必须输入一个模式中的随机数并不像设想的那样是随机数， 而却构成一些微妙的非随机模式， 那么整个的模拟(及其预测结果)都可能是错的。(Monte Carlo simulation)

脉冲编码调制（PCM）是数字通信的编码方式之一，在通信系统中完成将语音信号数字化的功能。PCM的实现主要包括三个步骤：抽样、量化、编码，分别完成时间上离散、幅度上离散及量化信号的二进制表示。(Pulse code modulation (PCM) is one of the encoding of digital communications, in a communication system will complete the function of digital speech signals. The realization of the PCM mainly includes three steps: sampling, quantization and coding, completed on the discrete time, the amplitude of discrete and quantify the binary representation of signals.)
