摘　　要：MATLAB是美国MathWorks公司开发的优秀数学软件,从矩阵范数和条件数的计算上可以看出MATLAB强大计算功能之一斑。当我们逐步地学会用计算机来处理大型数据的时候,我们收获的可能不只是精确的计算结果和提高的效率,还有对数学传统教育的反思。Matlab is a sort of outstanding math software developed by Math Work company of America, which shows powerful calculating functions through Matrix Norm and Condition Number calculation. As we learn gradually how to process large-scale data by computers, what we harvest are not only the precise calculation result and efficiency improvement but also the meditation on traditional math education.

关 键 词：矩阵范数 条件数 MATLAB计算 数学教育
