K Ninja Cydonia
This script yields each subset of size k from a super set of size n. There are two methods. The first operates on sets of integers of the form range(n). The seconds operates on arbitrary sets or lists.

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...
