Row Echelon Forms#
Definition: Row Echelon Form
A matrix \(A \in F^{m \times n}\) is in row echelon form if:
- All rows which contain only zeroes are at the bottom;
- The first non-zero entry of every non-zero row, called the pivot, is on the right of the pivot of every row above.
Note
A single matrix can possess more than a single row echelon form.

Definition: Reduced Row Echelon Form
A matrix \(A \in F^{m \times n}\) is in reduced row echelon form if:
- It is in row echelon form;
- All pivots are equal to 1;
- All entries above each pivot are zeroes.
