多维傅里叶变换，二维DFT快速算法，共分五部

是数据挖掘实验课上的一个作业，垃圾邮箱分类，给了57个属性1个分类目标，0是垃圾邮箱1不是，给了训练集和测试集，用的C++写的神经网络，并用遗传算法优化了，正确率96.5%，但是时间较长

AHP(层次分析法)的计算软件，可以进行一致性检验，虽然目前只能计算6阶以下的矩阵，但稍作修改即可扩充功能。-AHP (Analytic Hierarchy Process) calculation software can be tested for consistency, Although currently only six bands calculated the following matrix, but with some slight modifications can be expanded easily.

自动谱分析：可用于丢失/采样/子束光谱分析；矢量自动迭代，可用于建模，故障诊断；-The applications of this additional toolbox are: - Automatic spectral analysis for Irregular sampling/Missing data, analysis of spectral subbands, - Vector Autoregressive modeling and Detection [uses ARMASA] - Reduced statistics ARMAsel: A compact yet accurate ARMA model is obtained based on a given power spectrum. Can be used for generation of colored noise with a prescribed spectrum. - ARfil algorithm: The analysis of missing data/irregularly sampled signals - Subband analysis: Accurate analysis of a part of the power spectrum - Detection: Generally applicable test statistic to determine whether two signals have been generated by the same process or not. Based on the Kullback-Leibler index or Likelihood Ratio. - Analysis of segments of data, possibly of unequal length.
