WebBy means of a finite sequence of elementary row operations, called Gaussian elimination, any matrix can be transformed to row echelon form. Since elementary row operations preserve the row space of the matrix, the row space of the row echelon form is the same as that of the original matrix. The resulting echelon form is not unique; any matrix ... WebJan 22, 2024 · Multiply one row by a non-zero constant (i.e. 1/3, -1/5, 2). Now, we need to convert this into the row-echelon form. To convert this into row-echelon form, we need to perform Gaussian Elimination. First, we need to subtract 2*r 1 from the r 2 and 4*r 1 from the r 3 to get the 0 in the first place of r 2 and r 3.
