在Mathematica7.0环境下,实现了交互式矩阵初等变换。使用时只需选择矩阵初等变换的类型,并输入相应的变换参数,即可完成相应的初等变换并以可视化的方式显示矩阵初等变换的步骤及结果。在线性代数的教学中采用此交互式矩阵初等变换,可以在课堂中随时改变实例并进行演示来提高多媒体教学内容的灵活性。
This paper realized the interactive elementary operation of the matrix by using the Mathematiea7.0 software. When in use, users can execute the corresponding elementary operation and visually display the steps and results of elementary operation of matrix by selecting the type of elementary operation of matrix and inputting the corresponding operation parameters. In linear algebra teaching, teachers can change the instances and demonstrate the elementary operation at any time to improve the flexibility of the teaching content through the use of the interactive elementary operation of the matrix.
