Note that rref is computationally useless except very very very special occasions. So prefer LU decomposition if you have to. Share. Web12 years ago. In the process of row reducing a matrix we often multiply one row by a scalar, and, as Sal proved a few videos back, the determinant of a matrix when you multiply one row by a scalar, is the determinant of the original matrix, times the scalar. So you can clearly row reduce a matrix to the identity matrix but have a determinant ...
