核主成分分析方法是主成分分析的改进算法，其采用非线性方法提取主成分(Kernel principal component analysis method is an improved algorithm of principal component analysis, which uses a nonlinear principal components extracted)

用natlab将iris数据聚类为三类。然后将结果与虹膜数据集中的正确结果进行比较，并计算分类精度(You are offered the iris dataset of the UCI dataset. Cluster the data to three categories. Then compare the result with the correct one in iris dataset and compute the classification accuracy.)

说明：   此程序用提升法实现第二代小波变换 我用的是非整数阶小波变换 采用时域实现,步骤先列后行 正变换：分裂，预测，更新； 反变换：更新，预测，合并 只做一层（可以多层，而且每层的预测和更新方程不同）(procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different))

说明：  CT重建算法，迭代算法ARTII，乘型ART算法，该算法法比初始值选择不能为0(CT reconstruction algorithm, iterative algorithm ARTII, x-ART algorithm, The algorithm method than the initial value of options can not be 0)

压缩感知的各种重建算法，包括：CoSaMP，GBP,IHT,OMP,IRLS,SP算法(Compressed sensing various reconstruction algorithms, including: CoSaMP, GBP, IHT, OMP, IRLS, SP algorithm)

it is the matlab code of the imperialistic competitive algorithm.

说明：  使用matlab搭建模型进行电网三相全桥整流闭环控制(Closed-loop control of three-phase full-bridge rectifier in power grid using MATLAB model)

说明：  代码介绍全局平滑约束下的基于梯度光流法的MATLAB实现(Code describes the global smoothness constraint optical flow method based on the gradient of the MATLAB implementation)
