摘要
文章给出了利用左移位循环映射构造集合笛卡儿积的具体步骤,并从矩阵乘法运算的角度进行编程,在此基础上,给出了n个数码的所有全排列的构造程序,n阶行列式的计算程序等教学实验案例.本文给出的程序直观,简洁,易懂,适用于教学实验实践.
This article presents the specific procedure to construct the Cartesian product of several sets with left shift cyclic mapping,and carries on the programming from the angle of the matrix multiplication.On this basis,the article gives teaching experiment case of constructing the program of constructing all the full permutations of n numbers,and the program of n-determinant calculation.The program given in this paper is intuitive,concise and easy to understand,which is applicable to teaching experiment.
