WebSep 17, 2024 · Definition: Reduced Row Echelon Form. A matrix is in reduced row echelon form if its entries satisfy the following conditions. The first nonzero entry in each row is a 1 (called a leading 1). Each leading 1 comes in a column to the right of the leading 1s in rows above it. All rows of all 0s come at the bottom of the matrix. WebBy means of a finite sequence of elementary row operations, called Gaussian elimination, any matrix can be transformed to row echelon form. Since elementary row operations preserve the row space of the matrix, the row space of the row echelon form is the same as that of the original matrix. The resulting echelon form is not unique; any matrix ...
