题目
矩阵方程(010,100,001)X(100,001,010)=(1 -4 3,2 0 -1,1 -2
答案
[ 0 1 0]^(-1) [ 0 1 0 ]
[ 1 0 0] === [ 1 0 0 ]
[ 0 0 1] [ 0 0 1 ]
[ 1 0 0 ]^(-1) [ 1 0 0 ]
[ 0 0 1 ] =====[ 0 0 1 ]
[ 0 1 0 ] [ 0 1 0 ]
X=
[ 0 1 0] [ 1 -4 3 ] [ 1 0 0 ]
[ 1 0 0] * [ 2 0 -1 ]* [ 0 0 1 ]
[ 0 0 1] [ 1 -2 0 ] [ 0 1 0 ]
=
[ 2 -1 0 ]
[ 1 3 -4 ]
[ 1 0 -2 ]
举一反三
