Finite_difference_method
有限差分法
微分方程和积分微分方程数值解的方法。基本思想是把连续的定解区域用有限个离散点构成的网格来代替， 这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似， 积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组 ， 解此方程组就可以得到原问题在离散点上的近似解。然后再利用插值方法便可以从离散解得到定解问题在整个区域上的近似解。
(Finite Difference Method
Numerical solution of differential equations and integro-differential equation approach. The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution. And then using interpolation methods can be determined from the discrete solution of the problem solution of the approximate solution on the entire region)

text2img
This function was created as the function getframe() does not capture the data in the required size.
This function lets you specify the font size, weight and several other things.
* To change of background/font color open the file and make changes at appropriate places, as it is, it puts black text on white background.

Fuzzyclustering
模糊聚类；涉及事物之间的模糊界限时按一定要求对事物进行分类的数学方法。聚类分析是数理统计中的一种多元分析方法，它是用数学方法定量地确定样本的亲疏关系，从而客观地划分类型。事物之间的界限，有些是确切的，有些则是模糊的。例如人群中的面貌相像程度之间的界限是模糊的，天气阴、晴之间的界限也是模糊的。当聚类涉及事物之间的模糊界限时，需运用模糊聚类分析方法。模糊聚类分析广泛应用在气象预报、地质、农业、林业等方面。通常把被聚类的事物称为样本，将被聚类的一组事物称为样本集。模糊聚类分析有两种基本方法：系统聚类法和逐步聚类法。
