一维伽辽金型无网格法MATLAB程序 无网格方法采用基于点的近似，可以彻底或部分地消除网格，不需要网格的初始划分和重构，不仅可以保证计算的精度，而且可以大大减小计算的难度。然而，由于目前的无网格近似一般没有解析表达式，且大都基于伽辽金原理，因此计算量很大，要超出传统的有限元法；另外，无网格近似大都是拟合，因此对于位移边界的处理比较困难，多采用拉格朗日乘子法处理。-1维伽Galerkin-type meshless method MATLAB procedures meshless method based on the point of approximation, can be completely or partially eliminate the grid, the grid does not require the initial division and reconstruction, not only can guarantee the accuracy of the calculation, and can greatly reduce the difficulty of calculation. However, due to the current meshless approximation there is no analytic expression in general, and mostly based on the Galerkin principle, the calculation of a large volume, it is necessary to go beyond the traditional finite element method In addition, the meshless approximation are fitted, so displacement of the border more difficult to deal with, the use of Lagrange law.

A code which employs the SIMPLE-based pressure-correction method for solving the Navier-Stokes equations using Finite Volume method, Cartesian grid, and a colocated arrangement of variables.

数据流是用于许多不同的应用的一种重要模式：网络流量分析，传感器网络监控，运动对象的跟踪，金融数据分析。主要的挑战是：1）速度的挑战：数据正在进入该系统中的实时处理（例如，股票指数报价，传感器测量结果，网络流量）; 2）空间的挑战：数据通常是无界的某些职位上如何有效地存储和处理数据的另一个挑战。很多数据流应用的监控应用，其中的实时数据流进入系统体积庞大需要进行趋势分析和异常检测进行监控。关键的是要检测的模式和关系中可能存在的共同进化的数据流。流往往是内在相关性（例如，温度在同一栋大楼，在同一网络中主机的流量，在同一个市场，价格等），它可以减少几百个数字流逼到了一把隐变量的紧凑描述的主要趋势，并显着降低了进一步的数据处理的复杂性。
