Let A and B be A = [2 3 -1; 0 2 3; -2 3 0], B = [-2 3 0; 0 2 3; 2 3 -1]. Find an elementary matrix E such that EA = B. E = [; ; ]

Step 1
We can see that if we swap the first and second rows of A, we get B: A = $\begin{bmatrix} 2 & 2 \\ 3 & 3 \end{bmatrix}$ B = $\begin{bmatrix} 3 & 3 \\ 2 & 2 \end{bmatrix}$ Now, let's find the elementary matrix E that performs this operation. To swap the first Show more…
