利用基于排序的邻域粗糙集算法对具有高维属性的元数据进行属性约简，删减多余的无关属性，避免模型的过拟合，提高模型预测精度和模型运算速度(The algorithm based on the ordered neighborhood rough set is used to reduce the attributes of the high dimension attributes, to eliminate the redundant irrelevant attributes, to avoid the over fitting of the model, and to improve the accuracy of the model prediction and the operation speed of the model)

helpul code to finds the shortest path bounded

this help to draw delaunay triagles is input x,y to vectors represent coordinate of points for exemple p1(1,2) ,p2(3,4) p3(5,6) then x=[1,3,5] and y=[2,4,6]

用matlab分析由n个单胞组成的桁架在受到最外节点处的集中力是的位移及应力应变，并对整个结构进行优化设计。(Matlab analysis by single cell formed by the n truss subjected to the most outside the nodes in the concentration of power is the displacement, stress and strain, and the entire structure is optimized.)

LSH 和e2LSH算法，感觉hash函数不怎么好。(LSH and e2LSH algorithm, hash function is not very good feeling.)
