代码说明:

  Finite difference methods: Spatial discretization (3) Temporal discretization (2) Convergence, Consistency, Stability (2) Solution of PDEs require spatial and temporal discretization Typically, the spatially-discretized domain is called the grid The PDE (originally on a continuous domain) is solved on a discrete set of grid points Typically, the PDE is reduced to a set of algebraic equations (that might or might not involve matrix inversion) Types of grids: Structured grid Unstructured grid Hybrid grids

    此种模型绘制类似米字形的网格。由于整个过程递归调用绘图函数,所以可以根据误差判断绘制DEM的精细程度,从而绘制出不同精细程度的DEM,为解决漫游中数据量较大而引起的画面不流畅现象提供了模型基础。 本文并没有对LOD作研究,只是给出了四叉树的建立和遍历绘图的方法。 #include "Pt3d.h" //空间点类(主要记录空间点的x,y,z) (Rendering such a model similar to rice-shaped grid. Recursive calls as a result of the whole process of mapping function, so it can be judged according to the error map of the fine DEM, thus rendering a different degree of precision DEM, for the settlement of roaming in the amount of data arising from the larger screen does not provide a model of fluid based on the phenomenon. This article does not LOD for research, but given quadtree traversal of the establishment and mapping method.# Include Pt3d.h // space-point type (mainly recorded space points x, y, z))

    对人体信号时,先滤波再求频域,有助于研究生物等低频信号,十分有用。(Signal on the human body first and then seek the frequency domain filtering to help study biological and other low-frequency signals, very useful.)

  • 层次分析法
    说明:  层次分析法,简称AHP,是指将与决策总是有关的元素分解成目标、准则、方案等层次,在此基础之上进行定性和定量分析的决策方法。(It refers to the decision-making method that divides the elements that are always related to decision-making into objectives, criteria, schemes, etc. on the basis of which qualitative and quantitative analysis can be carried out)
