用最少几轮来设置一个字符串，放弃一些引用，用字符来代替字符，以满足和字符串有关的目的

成绩等级,分成优秀良好中等合格不合格输入成绩自动完成分类-Achievement levels, divided into good middle-outstanding achievements qualified unqualified input auto-complete classification

经典的插值算法，我找人要的，真的很难得！记得顶啊！-Classical interpolation algorithm, I want someone to really hard to get!顶啊remember!

基于MPI的并行快速排序算法，可以通过并行快速排序提高排序速度-MPI-based parallel quick sort algorithm, you can sort through parallel quick sort to improve the speed

是用来生成测试数据的类，可以直接生成测试人员需要的各种数据-Is used to generate test data type, you can directly generate test data needed

这是我们数学建模用的MATLAB喷泉代码实现，模拟的很好哦！代码在最后面-This is what we used mathematical modeling fountain MATLAB code to simulate Oh well! Code in the final surface

画函数图象的matlab程序,很实用，希望和大家分享。-Matlab image draw function, procedure, very practical, would like to share.

由于一个数值问题的精确解往往事先不知道，而用数值方法求出的计算解的误差又是不可避免的。因此，数值解是否失真，如何判断──即误差问题，成为大家所关心的重要而又困难的问题，本章只介绍了误差的基本概念和数值计算的若干原则，这对处理数值计算问题是必需的，但是仅这些还远远不能解决工程和科学计算中更为复杂的误差分析问题，还需专门分门别类地进行研究。-as an accurate numerical solution of the problem often did not know in advance, and the numerical methods used to calculate the solution sought by the error is inevitable. Therefore, the numerical solution of whether distortion, how to judge-- namely error, as we are concerned the important and difficult issues, this chapter presents only the basic concept of error and numerical calculation of certain principles, which deal with numerical calculation is necessary, but they are far from alone can not solve engineering and scientific calculations more complex error analysis, specialized categories needed to conduct research.

并行环境下实现生灭问题。上传的两个都是分布式并行处理的经典案例的实现。-Parallel realization of birth-death issue of environment. Upload two are a classic case of distributed parallel processing implementation.
