有限元算法求解铁木辛柯梁梁静力问题实例。一个简单的一维梁模型，用FEM算法求解，用于学习有限元编程。(Timoshenko beam in bending)

基于“脉动”结构 求 任意偶数阶实对称阵的特征值，用于MIMO通信反馈信道质量，已经在实际产品实现。( 注：脉动结构只需O(n*log(n))量级运算，高效快速)("Systolic Arrays" structure based Eigen Value Decomposition)

说明：  reads vectors dynamically

输入的影像可以是一个复杂的形象contaning点，纹理，缺陷等图形用户界面可以让用户手动识别中心，动态更新和纪念中心。标志着该中心可以在整个图像或它的一部分。一旦所有这些中心鉴定，RDF是由程序计算和策划，并包含一个txt文件保存中心的名单。(The input image can be a complicated image contaning dots, textures, defects etc. The GUI lets the user manually identify the centers, dynamically updating, and marking the centers. The centers can be marked in the whole image or a part of it. Once all the centers are identified, the RDF is calculated and plotted by the program, and a txt file containing the list of centers is saved. )
