## Two matrices are said to be row equivalent if one can be obtained from the other using elementary row operations.

## A matrix is in row-echelon form if:

- All rows consisting entirely of zeros are at the bottom.
- In each row that is not all zeros the first entry is a 1.
- In two successive nonzero rows, the leading 1 in the higher row is further left than the leading 1 in the lower row.
