The Gauss-Jordan Elimination Algorithm

Echelon Forms Reduced Row Echelon Form De nition A matrix A is said to be in reduced row echelon form if it is in row echelon form, and additionally it satis es the following two properties: 1 In any given nonzero row, the leading entry is equal to 1, 2 The leading entries are the only nonzero entries in their columns.

Methods for Finding Bases - Texas A&M University

Corollary 1.2 Let U be the reduced row echelon form of a matrix A. Then, the number of nonzero zero rows in U, the number of leading entries in U, and the number of leading variables in the corresponding homogeneous sustem Ax= 0 all equal rank(A). As an example, consider the matrices A and U in (1). U has two nonzero
