Homework Statement
I have a matrix 1, 0, 1/12, 1/12 | 1/12, 0, 0, 0
0, 12, 143/12, 11/12 |-1/12, 1, 0, 0
0, 12, 143/12, 11/12 |-13/12,0,1,0
0, -12, -143/12, -11/12|-11/12,0,0,1
---------------------------------------------------
1 , 0, 0 , 0 |
0, 1, 0 , 0 |
0, 0, 1, 0 |
0, 0, 0 , 1 |
And I can't understand how can one get the following block matrix from the previous one with elementary row operations:
1, 0, 1/12, 1/12 | 1/12, 0, 0, 0
0, 12, 143/12, 11/12 |-1/12, 1, 0, 0
0, 12, 143/12, 11/12 |-13/12,0,1,0
0, -12, -143/12, -11/12|-11/12,0,0,1
---------------------------------------------------
1 , 0, -1/12 ,-1/12 |
0, 1, 0 , 0 |
0, 0, 1, 0 |
0, 0, 0 , 1 |
And ideas?
