Fast Fourier transform

SelfOrganizingMap 或 SOM 神经网络算法对聚类的数据集，可以在 Weka 程序中嵌入

一个矩阵类的实现，有加减乘除、求逆、转置等功能，应该是一个不错的实用程序。-a matrix of type, and it is the arithmetic, inversion, transpose function, it should be a good utility.

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.

学习NURBS时写的NURBS曲线曲面的库-NurbsLib,用它就可以画NURBS曲线和曲面了。里面的源代码参照了The NURBS Book, 注意该程序只能编译出来库文件，NurbsCurve.lib和NurbsSurface.lib如果想画NURBS曲线和曲面还要自己建立OPENGL三维环境，根据节点矢量和权因子等调用该库绘制曲线和曲面。同时注意使用了matrix.h的头文件实现矩阵运算。

人脸识别，是基于人的脸部特征信息进行身份识别的一种生物识别技术。用摄像机或摄像头采集含有人脸的图像或视频流，并自动在图像中检测和跟踪人脸，进而对检测到的人脸进行脸部的一系列相关技术，通常也叫做人像识别、面部识别。

各种算法的c语言程序，包括huffman、线性表、栈、队列等--All kinds of algorithm program in C language, including huffman, lineartable, stack, queue etc.

C Source Code program of FFT IFFT Function

利用该程序，可以作为相应程序的一个函数功能-Use of the procedure, the procedure can be used as a function of the corresponding function

#include #include using namespace std;//变量声明 class EiNum; #define MAX 20//MAX为最大的迭代深度 int depth;//当前树的最大深度 EiNum * root[MAX + 1];//重复当前的路径 //交换两个数 void Swap(int &a,int &b) { int temp; temp = a; a = b; b
