说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

《MATLAB神经网络30个案例分析》中的第14个例子，案例14 SVM神经网络的回归预测分析---上证开盘指数预测。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 14 cases (14 of SVM neural network predictive regression analysis- Shanghai opened index prediction. Hope to have certain help to everybody! )

梯度下降法在二维函数中的优化寻优，老师上课的例子，可以运行无误(Gradient descent optimization in a two-dimensional function optimization, teacher in the class example, you can run correctly)

this is the test of generate guassian random variable

小区初搜为GSM系统中的一个关键过程，本程序为GSM小区初搜过程查找并解广播控制信道bcch的matlab程序，输入数据由采样数据得到，在转换成所需格式后进行处理。若其中包含bcch,则输出找到信息，并通过解调译码等工作解其中信息信息。若没有，则发出错误信息。内付算法详细说明文档(Area early in the search for the GSM system, a key process, the procedures for the GSM cell and the beginning of search process to find solutions BCCH Broadcast Control Channel of matlab procedures, input data from the sampling data, converted into the desired format in the post-treatment. If one includes bcch, while the output to find information and work through the demodulation decoding information in which information solutions. If not, then send a wrong message. Pay the algorithm in detail within the document)
