matlab code for generating eye diagram for qpsk

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

This code is used to create input files for the 2D FEM solver used in ME 413 course. It uses the freely available mesh2d mesh generator to create the mesh.

用matlab编的游戏，还真没想到matlab能编出游戏来(Game series with matlab, matlab really did not expect to be able to compile the game)
