Reduced Row Echelon Form
... 1. The first non-zero entry in any row is the number 1, these are called pivots. (So each row can have zero or one pivot.) 2. A pivot is the only non-zero entry in its column. (So each column can have zero or one pivot.) 3. Rows are orders so that rows of all zeros are at the bottom, and the pivots ...
