设矩阵A=(3 0 0 0 1 -1 0 1 4 )B=(3 6 1 1 2 -3 )且满足AX=2X+B,求矩阵X

问题描述:

设矩阵A=(3 0 0 0 1 -1 0 1 4 )B=(3 6 1 1 2 -3 )且满足AX=2X+B,求矩阵X
3 0 0 3 6
设矩阵A=0 1 -1 B=1 1
0 1 4 2 -3
且满足AX=2X+B,求矩阵X

(A-2E)X=B
x=(A-2E)^(-1)B
令C=(A-2E)则
x=C^(-1)B
C^(-1)= (1.0.0;0.-2,-1;0,1,1)
X=(3.6;-4.1;3.-2)有详细一点的么??字节这样写就给分,还要详细的?
