roughset
,在MATLAB环境下对
学生自主学习成绩决策表进行了求解,分析了该决策表的上近似集、下近似集、不可分辨关系、约简、核集、属性依赖度的概念,从而
在原始数据的基础上得出了条件属性与决策属性间的关系。
(The knowledge theory based on rough set can help to simplify the knowledge proceeded from originaldata. In the paper it intro-
duces the rough set theory and its principle algorithms. MATLAB Rough SetToolbox is programmed to analyze the decision table of self-learn-
ing system from students score database.The concepts such as the upper approximation, lower approximation, indiscernibility relation, reduc-
tion, core set, and attribute-importance are analyzed based on the score database table.Thus, the relations between condition attributes and de-
cision attributes of the score database are obtained on the basis of original data.

Gauss_Seidel_iterative
迭代法是解线性代数方程组的另一类方法,特别适用于解大型稀疏线性方程组。它的基本思想是针对求解问题预先设计好某种迭代格式,从而产生求解问题的近似解迭代序列,在迭代序列收敛于精确解的情况下,按精度要求取某个迭代值作为问题解的近似值。迭代法具有原始系数举证始终不变,算法简单,编写程序较方便,所需存储单元较少的优点。(iterative method was the linear algebraic equations of the other methods, particularly applicable to the large sparse linear equations. The basic idea is to solve the problem in advance against the design iteration some good format, thereby creating problems for the approximate solution of iterative sequence, the iterative sequence converges to the exact solution, precision demanded by a certain value as a question iterative solution approximation. Iteration with the original proof coefficient remains unchanged, the algorithm is simple, the preparation process more convenient, less required storage unit advantages.)
