【摘要】 线性方程组模型是数学建模的一种常见模型，以分区数独为例，按照建模基本步骤建立非齐次线性方程组模型，利用Lingo软件编写程序求解，用数独段位考试练习题进行验证．将建模及求解的思想方法推广，建立节点数独的线性方程组模型，并编写程序求解．数学建模训练实践表明，建立数独的线性方程组模型并利用Lingo软件编程求解具有实用性和有效性，建模培训中引入此类例题，可以激发学生学习兴趣，提高培训效果．更多还原

【Abstract】 The linear equations model is a common model for mathematical modeling,taking partition Sudoku as an example,the non-homogeneous linear equations model is established according to the basic steps of modeling,and is solved by using Lingo software to write a program,then the Sudoku level exam practice problems were used to verify the linear equation model.The idea of modeling and solving is extended to establish the linear equations model of node Sudoku and a program is given to solve it.Mathematical modeling training practice showed that it is practical and effective to establish the linear equations model of Sudoku and use Lingo software programming to solve it. The introduction of such examples in modeling training can stimulate students′ interest in learning and improve the training effect.更多还原
