Our basic idea is based on (n,k)-gray code which was introduced in one paper named :"Generalized Gray Codes with Applications". Our extention is allowing each digit ranged from different digit which is widely useful in some situations.For example, (3,2)-Gray code is (0,0), (0,1),...

isParetoSetMember returns the logical Pareto membership of a set of N points in K dimensions. It takes as input a N-by-N matrix and return a N-binary-array, denoting for each of the N points, whether it is Pareto (1) o not (0).The concept of Pareto dominance considered herein is the standard...

This is just a brute force implementation of k nearest neighbor search without using any fancy data structure, such as kd-tree. However it is the fastest knn matlab implementation I can find.A partial sort mex function is implemented which is a simple wrapper of c++ partial_sort.Provided the sort...
