Galerkin方法,这是一种真正的无网格方法.这种方法采用移动最小二乘函数采近似解变量,并且采用移动最小二乘近似函数的权函数作为加权残值法的权函数.文中对形成的离散动力学方程用Newmark方法求解(Galerkin method, this is a real meshless method. This method adopts moving least squares in function approximation solution variables, and adopts moving least squares approximate function of weight function as a weighted residual method of weight function. In the paper, the discrete dynamic equation formed with Newmark method to solve)

为实现合成孔径雷达（SAR）图像分类算法的测试与评估，将VC/Matlab 混合编程技术应用到SAR 图像分类平台开发中，分析与 比较了4 种VC/Matlab 混合编程方法及各自优缺点，并着重研究了基于组件对象模型（COM）的VC/Matlab 混合编程方法。使用Matlab COM 编译器创建了SAR 图像分类算法组件，在VC 中调用其导出的接口函数。在此基础上，完成了SAR 图像分类平台的实例开发且 可脱离Matlab 环境运行。实验结果表明，该方法较好地发挥了VC 与Matlab 各自的优势，提高了SAR 图像分类平台开发的效率。(In order to test synthetic aperture radar （SAR） image classification algorithm，VC/Matlab mixed programming technology was used in SAR image classification platform development. Four VC/Matlab mixed programming methods were introduced and analyzed. Comparing with other three methods，the method based on component object model （COM） was studied particularly. SAR image classification algorithm component was created by Matlab COM complier，and its interface function could be invocated with VC. Using this method，a SAR image classification platform was realized. The platform could run without Matlab. The experimental result shows a good combination of VC and Matlab. So，developing efficiency could be enhanced a lot.)

此程序实现图象增强的功能，采用直方图均衡化的方法来实现图像增强。(This procedure realize the function of image enhancement using histogram equalization method to achieve image enhancement.)

MATLAB用于非线性方程组的求解问题，用的方法是牛顿迭代法(the solution of nonlinear functions)

对于具有关心的机械，采用2次函数进行预测，然后采用估计反求其合理值点(first we predict the possible velocity and then reverse the time and valuse by quadratic function)

为了有效提取面邵表情特征，提出了一种新的基于LBP(局邵二值模式)特征的人脸表情识别特征提取方法首先用均值方差法对表情图像进行灰度规一化，通过对图像进行积分投影，定位出眉毛、眼睛、鼻和嘴巴这些关键特征点，进而划分出各特征邵件所在子区域，然后对子区域进行分块，提取各个子区域的分块LBP直方图特征(Abstract: In order to effectively extract facial expression feature,a novel facial feature extraction approach for facial expression recognition based on Local Binary Pattern(LBP) is proposed in the paper )

说明：  人脸检测的程序和文章，基于matlab。(face detection )

最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)
