WebSelect a nonzero entry in the pivot column as a pivot. If necessary, interchange rows to move this entry into the pivot position. Use row addition operations to create zeros in all positions below the pivot. Cover (or ignore) the row containing the pivot position and cover all rows, if any, above it. apply steps 1-3 to the submatrix that remains. Web1. All zero rows are at the bottom of the matrix. 2. The leading entry of each nonzero row after the first occurs to the right of the leading entry of the previous row. 3. The leading entry in any nonzero row is 1. 4. All entries in the column above and below a leading 1 are zero.
1.2 Row Reduction and Echelon Forms
Many of the problems you will solve in linear algebra require that a matrix be converted into one of two forms, the Row Echelon Form (ref) and its stricter variant the Reduced Row Echelon Form (rref) . These two forms will help you see the structure of what a matrix represents.
