WebAug 23, 2024 · Edit - Maybe the theory is suggesting that each matrix in row echelon form has one unique reduced row echelon form, but since I got a different row echelon … Web4. It depends on WHY you're wanting to reduce it. If you're trying to determine if a matrix is invertible -- then yes (that is you're checking to see if the matrix is similar to the identity matrix). You can use either one or both together. In general, though, row and column reduction are 2 different things.
