FFT算法C语言实现 和MATLAB中fft函数结果一样的功能(FFT algorithm C language and MATLAB fft function results in the same function)

这是基于ARM9开发板写的LED驱动测试代码，能够达到开关灯，流水灯等效果。这只是个例子代码，不做实际使用，不过是很好的驱动模板，大家可以学习学习，观摩观摩。大家一起学习。谢谢大家的支持。

基于数据库的VC++提醒精灵软件，设置好日期、时间、内容，就会在指定的日期、时间提示，须确定看到提示，否则两分钟后又提示。修改，删除，查询，日期，待自动启动到时间一会提示。 　　其中包括一个数据库操作类觉得不错，这个类是CPingDatabase，能插入、修改、查看、删除ACCESS数据库、SQLSERVER及所有的ODBC得用数据源来连接的数据库。使用类时出现一个警告，不用管它，那是微软的一个动态的原因。 (VC++ based on database software to remind the wizard, set the date, time, content, will be in the specified date, time, tips, to be sure to see tips, or two minutes later prompt. Modify, delete, query, date, to be automatically activated to the time for a prompt. Including a class of database operations that good, this class is CPingDatabase, to insert, modify, view, delete the ACCESS database, SQLSERVER and all ODBC starting a data source to connect to the database. A warning when using the class, do not ignore it, that is the reason Microsoft is a dynamic.)

1）利用CC++语言实现给定的LFSR； 2）通过不同初始状态生成相应的序列，并观察它们的周期有什么特点； 3）利用生成的序列对文本进行加/解密（按对应位作模2加运算）。 给定的LFSR为：(1) the use of C C++ language given LFSR 2) to generate the corresponding sequences by different initial state, and observe what are the characteristics of their cycle 3) using the generated sequence of text encryption/decryption (press the corresponding bit for modulo-2 addition operation). LFSR given as follows:)

指纹识别算法源代码，程序需要imagemagic的支持，imagemagic可以在网上搜索到最新的版本（程序在图像 的输入/保存代码处用了imagemagic的函数，如果读者不想使用imagemagic，可以修改 程序有关图像存取的部分，改成自己的图像存取函数，这部分的工作量不是太大）。 代码可以在Linux下面编译通过。(Fingerprint recognition algorithm source code, procedures need to imagemagic support, imagemagic available online english to the latest version (the procedure in the image input/save code Department spent imagemagic function, if readers do not want to use imagemagic, can modify the program to access the relevant image part, into its own image access function, this part of the workload is not too much). Code can be compiled following the adoption of Linux.)
