Row reduced echelon form using determinant

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 … WebThe 3-by-3 magic square matrix is full rank, so the reduced row echelon form is an identity matrix. Now, calculate the reduced row echelon form of the 4-by-4 magic square matrix. Specify two outputs to return the nonzero pivot columns. Since this matrix is rank deficient, the result is not an identity matrix.
