这个是用Visual C++实现的计算器源代码，经过调试可行

这个项目的目的是决定两文本实例的相似度，并举例支持中文处理。

The importance of direct methods discussed in the previous work is unquestionable, since in some practical engineering problems, information about the values of the objective function is the only reliable information, which may have a researcher.

用幂法与反幂法求矩阵的最大特征值及最小特征值-with power law with the anti-power method for matrix eigenvalue of the largest and the smallest eigenvalue

查表型crc16校验算法，c源码-Lookup- crc16 checksum algorithm, c FOSS

order发计算光子晶体的能带结构，比较好-order issued calculation of photonic crystal band structure, good! !

md5的加密算法.一个工程文件.很好的用来学习,研究-md5 encryption algorithm. a project file. very good for study, research

This program will ask how many numbers you want to find the average of, then it will allow you to enter your numbers(yes they can even be decimals) then it will calculate the mean, median, mode and range of what you enter.
