Hey guys i am stuck with the gaus jordan method of the following matrix.
A = 1 2 3
4 5 6
3 1 -2
For the co factor i worked out the C transpose as:
1/3 (-16 7 3
26 -8 6
-11 5 -3)
The gaus jordan is suppoesed to agree with my final cofactor matrix but i can't seem to understand how to get there?? i have donw the row eliminations to get the diagonal as 1 and the rest as 0.
Add (-4 * row1) to row2
Add (-3 * row1) to row3
Divide row2 by -3
Add (5 * row2) to row3
Divide row3 by -1
Add (-2 * row3) to row2
Add (-3 * row3) to row1
Add (-2 * row2) to row1
But now i don't understand what i have to do now?
