Step-by-step explanation:
educed Row Echelon Form
A matrix is in row echelon form (ref) when it satisfies the following conditions.
The first non-zero element in each row, called the leading entry, is 1.
Each leading entry is in a column to the right of the leading entry in the previous row.
Rows with all zero elements, if any, are below rows having a non-zero element.
A matrix is in reduced row echelon form (rref) when it satisfies the following conditions.
The matrix is in row echelon form (i.e., it satisfies the three conditions listed above).
The leading entry in each row is the only non-zero entry in its column.
A matrix in echelon form is called an echelon matrix. Matrix A and matrix B are examples of echelon matrices.
