elementary matrix. I think it has something to do with the column but i thought it had to be row operstions
Question: find an elementary matrix E such that AE=B
i am given A = 2 4
1 6
B= 2 -2
1 3
i set it up like
(2 4|1 0) = (2 -2)
(1 6|0 1) (1 3)
the 2 and 1 are good but i cant do anything to the 4 and 6 without changing the 2 and 1 which i want to leave. Any thoughts?
