使用队列模拟理发馆的排队现象，通过仿真手法评估其营业状况。-use cohort simulation barber"s shop, the queues, through simulation methods to assess its financial situation.

里面包括了c++的各章的教程和网址内容，可以从很基础的讲起，包括了安装，感受，经典篇，还有就是各种函数，安装库，比如：SDL,xsd，gSOAP,codeblocks的配置等。。。

this program is describe the berkeley and christian algorithm, the language is programming by java 这是两个用Java语言编辑的算法，你可以很好地知道，明白两个算法的理论知识

用c编写的简单的计算器，用鼠标工作,实现基本的计算器功能-prepared with a simple calculator, with the mouse work, the basic function calculator

克鲁斯卡 （Clsk） 求最小生成树-unmarked (Clsk) for the minimum spanning tree

采用按列消去，舍入误差并没得到很好的处理，有待改进。-adopted by the elimination series, rounding error not been handled well, in need of improvement.

程序包含了显示类中二维显示和三维显示的关键技术，程序在VC6.0下调试通过，显示类的定义部分在eidterView.h 文件中， 其实现部分在 eidterView.cpp文件中，显示包括了 显示图形和方向函数以及三维情况下函数图形的显示，任何人可以在此基础上加以修改完善

误差分析的方法有多种，这是一种先验估计误差的方法，较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果，以而使矩阵的误差分析获得了突破性的进展，使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。特别值得一提的是，在工程技术界，经常使用几种不同的计算方法，甚至使用实验方法进行比较，从而确定计算结果的可靠性，这也是一种有效而实用的方法。-error analysis by a number of means, which is a priori estimation error method, compared to the previous "Forward Error Analysis" in the matrix calculation error into the homes a better estimate on the results of a matrix so the error analysis of a breakthrough in the progress, many with forward error analysis can be difficult to determine on the numerical method to achieve new progress. Particularly worth mentioning is that in the engineering technology sector, often use several different methods of calculation, or even the use of experimental methods, in order to determine the reliability of results, which is also an effective and practical method.
