naive bayes分类法的matlab实现，包含训练和测试部分(naive bayes classification matlab realize, including training and testing parts)

采用爬山法求解优化问题，一共4个文件，函数和脚本分开放(Climbing method used optimization problem, a total of four documents, functions and sub-script open)

在ar人脸库上实现Direct Fisher discriminant analysis,该方法首先对类内散布矩阵对角化，然后对类间散布矩阵对角化，使类间散布矩阵对角化的矩阵即使鉴别向量集(In the ar face database to achieve Direct Fisher discriminant analysis, this method first within-class scatter matrix diagonalization, and then between-class scatter matrix diagonalization, so that between-class scatter matrix diagonalization of the matrix even if the identification of a vector set)

3GPP LTE采用的信道仿真模型，目前在3GPP中的提案均采用这一种信道模型，源码是经过国外著名大学和公司联合完成的，极具珍藏价值。(3GPP LTE the channel simulation model, 3 GPP in the proposal were adopted this channel model. OSS was famous overseas universities and companies jointly complete the great commemorative value.)
