【摘要】Integral matrices and permutation matrices are the two kinds of important matrices in matrix theory. We solve two matrix problems using mathematica in this paper.One is how to determine whether some matrix is integral matrix and the other is to generate all permutations of some given matr...

In SymPy, matrices are created as instances from the Matrix class: In [1]: from sympy import Matrix In [2]: Matrix([ [1, 0 , 0], [0, 1, 0], [0, 0, 1] ]) Out[2]: ⎡1 0 0⎤ ⎢ ⎥ ⎢0 1 0⎥ ⎢ ⎥ ⎣0 0 1⎦ It is possible to slice submatrices,...
