Fast Fourier Transform code

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

一个关于数据挖掘的决策树算法-a data mining on the Decision Tree Algorithm

数值计算算法：方法错误的定位写帕斯卡尔要找到一个解决方案，以F（X）=0给出的连续函数   f。关于区间[P0，P1]，其中f（P0）和f（p1）为必须   相反的迹象：   输入：端点P0，P1;公差TOL;            迭代N 0的最大数目。   输出：近似解p或            该算法失败的消息。

基于MFC对IGES文件进行解析并分流存储，采用数学算法完成NURBS模型统一建立，最后利用OpenGL完成NURBS模型重绘并进行交互操作。

这是我从网上找到的阴历算法，出于对原作者的尊重，代码里的各内容多于保留。-This is what I found in the lunar calendar online algorithm, based on the original author of respect, the code"s content than reservations.

资源描述void show2() //加密界面 {  printf(" ****************** DES加密 ********************** ");  printf(" -------------------------------------------------- ");  printf(" ************************************************** ");  printf(" ** ** ");  printf(" ** 请选择明文和密钥的输入方式: ** ");  printf(" ** ** ");  printf(" ** 1.直接输入 ** ");  printf(" ** ** ");  printf(" ** 2.从文件读取 ** ");  printf(" ** ** ");  printf(" ** 3.退出 ** ");  printf(" ** ** ");  printf(" -------------------------------------------------- ");  printf(" 选择:"); }

通过图形界面上数据的输入，将进程的所需的最大资源数、已分配资源数、完成进程所需的剩余资源数数据存入数组中，再根据银行家算法要求，进行进程间的运行分配，而后显示在左侧的面板上。

此代码有着卓越的时间优越性，能大大增加代码的可读性。同时，代码中还有高效性！
