MATH 17100 2844611/09/2009 The row-reduced echelon form An mnmatrix is in row-reduced formif it has the following properties: (1)The first non-zero element encountered along any row is 1. Such an element is called a pivot element. (2)Along the columnwhere a pivot element is located, all other elements are 0. (3)Zero rowsoccur below non-zero rows. (4)The pivot elementin any row occupies a column to the right of the pivot element above it. Any given matrix can be brought into row-reduced form, and that row-reduced form is unique for the given matrix, by application of the elementary row operations, namely row exchanges,
