Webthere are two natural ways to associate the permutation with a permutation matrix; namely, starting with the m × m identity matrix, I m, either permute the columns or … WebApr 28, 2024 · 2 Answers. Use P = [ 1 0 0 0 0 1 0 1 0]. The first column of P ensures that the first row of A does not change. The other two columns then swap the second and third row. If you swapped the second and third column in P then P would be the identity matrix and all rows in A (and the columns too) would remain in their place.
