K最近邻C实现，测试通过，可以使用，主要适用于数据库定位方法-K nearest neighbor C implementation, the test passes, you can use, mainly applied to the database location method

室内定位算法，最近邻算法，K最近邻算法，加权K最近邻算法，贝叶斯算法-indoor position locatian ,including nn,knn,wknn,bayes.the algrithm compare the different of the above method and get some useful conclusion.

经典的分类算法，可以完成基本的分类。。。(Classic classification algorithm, you can complete the basic classification...)
