联想分为自联想和异联想，应用matlab实现神经网络的联想记忆功能。(Since the association and the association is divided into different association, the application of neural network matlab realize the associative memory function.)

应用matlab进行数独解密的算法和教程，英文版，来自matlab创始人(The Userguide to use matlab to solve sudoku)

已知空间三个点的坐标，求通过三个点的圆的圆心和半径，输入为三个点(Known spatial coordinates of three points, three points of the circle which passes through the center and radius, enter three points)

this code is for iris image enhancement using gaussian filter

函数mean5_3(五点三次平滑算法)对数据进行平滑处理的源代码 (Function mean5_3 (five-point smoothing algorithm three times) to smooth the data source)

说明：  正弦波，方波，三角波三种波形的FM、PM调制解调(Modulation and Demodulation of Three Waveforms: Sine Wave, Square Wave and Triangular Wave)

说明：  最小二乘支持向量机的matlab工具箱，包含几乎所有常用的支持向量机应用函数。(Least squares support vector machines matlab toolbox, including almost all commonly used applications of support vector machine function.)

采用matlab实现的wsn节点算法，对于研究wsn非常有好处。虽然有很多人有类似的代码，但是这个代码比较相信。(Using matlab to achieve wsn node algorithm for the study of wsn very good. Although many people have similar code, but this code is to believe.)

该源码使用C4.5算法进行分类，该程序为matlab源码。(Classify using Quinlan s C4.5 algorithm)

傅里叶变换后频谱图 B：陷波函数作用后的频谱图 C：经逆变换的滤波后图像，效果不是很理想 Ifft2：为验证自己的快速傅里叶变换程序的正确性，用matlab自带逆变换程序将频谱逆变换后图形，与原图相符，说明快速傅里叶变换程序正确。(This is a FFT )
