采用matlab里面的线性回归函数regress进行的分析，还画出了三维图。(Based on matlab inside of linear regression function regress analysis and drew out the 3d map.)

以梯度投影法迭代直接求解出观测值的改正数，给出一个简单算例，以资验证。 (The correction of the observation is obtained by the interation with gradient projection method and a simple calculation example is given to verify it)

分析一维波动方程的各种格式精度等特性，附按钮界面，一共七种格式，可在代码中修改步长，时间等等，展现动画(analysize seven schemes for one-dimensional wave equation with animation.)

This folder Contains one file file of code of cognitive femtocell, second computing distance and third also computing path loss. We consider smart “cognitive” femtocells, that can decode the base station control channel and make decision on their transmission opportunities based on the scheduling and resource allocation of the overlaying macrocell. The operation of such femtocells is somehow reminiscent of “Type II” relays, as specified in the IEEE 802.16j standard. Under certain system assumptions, we consider the tradeoff region of the macrocell versus aggregate femtocell throughput

《MATLAB神经网络30个案例分析》中的第22个例子，案例22 LVQ神经网络的预测——人脸朝向识别。希望对大家有一定的帮助！ (The MATLAB neural network analysis of 30 cases of 22 example, 22 cases of LVQ neural network prediction, face toward the identification. Hope to have certain help to everybody!)
