compute dft matrix, creates a W matrix of size N

function g=distance_classify(A,b) 距离判别法程序。 输入已分类样本A（元胞数组），输入待分类样本b 输出待分类样本b的类别g 注：一般还应计算回代误差yita 输入已知分类样本的总类别数n 每类作为元胞数组的一列(function g = distance_classify (A, b) from the Criterion procedures. Input samples have been classified A (cell array), the importation of samples for classification b output samples for classification g categories b Note: the calculation should also be back on behalf of the general error input yita of the total known types of classification of the number of samples n each Cellular-type array as a)
