用Excel来演示解线性方程组的过程

探讨了Excel的数值计算功能，阐述了用这些功能在电子表格上直接进行初等变换的计算过程。并用Microsoft Excel的公式复制功能演示迭代法解线性方程组的迭代结果，最后指出了使用Microsoft Excel演示解线性方程组时应注意的问题。

Demonstrating the processes of solving the set of linear equations by Microsoft Excel

The teaching of mathematics class emphasizes processes of proving and solving problems. In the teaching, the teacher must demonstrate clearly the process to students step by step. In the teaching of elementary transform and solving set of linear equations in linear algebra, due to more data and steps, mistakes occur easily, It follows a bad effect on understanding of mathematics senses. The Microsoft Excel has higher numerical functions and automatic re-calculating function, It directly computes vectors and matrices in the forms, and may demonstrate the processes of elementary transform and elimination of set of linear equations by arithmetical array functions of Microsoft Excel and, perform iteration of set of linear equations by formula-coping and auto-computing functions of Microsoft Excel.
