WebWe say an n m matrix A is in reduced row echelon form (rref ) if the following are true of A: (1) Each non-zero row has rst non-zero entry equal to 1 (called leading 1 or pivot). (2) If a column contains a pivot, then every other entry in the column is zero. (3) As one moves down the rows, the pivots move strictly to the right. All zero WebTo get the matrix in the correct form, we can 1) swap rows, 2) multiply rows by a non-zero constant, or 3) replace a row with the product of another row times a constant added to the row to be replaced. Here is an example: Solve the following system of equations : . Find the first non-zero entry in the first column; this is the pivot. WebExample 3: Converting a Matrix to Echelon Form. Describe the row switches which are necessary to put the following matrix into echelon form: ⎛ ⎜ ⎜ ⎝ 0 3 4 0 0 0 2 2 − 2 0 0 4 ⎞ ⎟ ⎟ ⎠. Answer . We observe that the second row is a zero row.
