Simple and effective means of clustering any data for which a similarity matrix can be constructed. Does not require similarity matrix meet the standards for a metric. The algorithm applies in cases where the similarity matrix is not symmetric (the distance from point i to j can be different from j to i). And it does not require triangular equalities (e.g. the hypoteneus can be less than the sum of the other sides)

this is used to define table data in matlab gui

KPCA程序，可用于数据降维，特征提取，用起来比较简单(KPCA procedure can be used for data dimensionality reduction, feature extraction, using relatively simple)

觉得很好的一个Matlab程序想和大家一起分享，互相学习。(A Matlab program feel good and you want to share, learn from each other.)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大，出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (BP network in strict accordance with the formula to design a matlab program, the optimized BP network design optimization 1: Design of the yyy, that is, o (k) formula, when the network into the flat areas (< 0.0001) increase learning rate large, after the optimization of learning rate reduction 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j) )

这里面包含了在matlab中实现傅里叶变换的各种源程序(This contains the Fourier transform of a variety of source code in matlab)

说明：  基于AHP的专家遴选，先对判断矩阵的一致性进行判断，不满足时，对单个元素进行步长和方向的调整。(AHP-based expert selection, firstly， to judge the consistency of the comparison matrix, when not satisfied, make adjustment of the step size and the direction of individual elements .)
