WebElimination produces an upper triangular system, called row echelon form for Gauss elimination and reduced row echelon form for Gauss--Jordan algorithm. The Gauss elimination introduces zeroes below the pivots, while Gauss--Jordan algorithm contains additional phase in which it introduces zeroes above the pivots. WebYou can also put a matrix in reduced row echelon form. We could put the augmented matrix. Use the text “row reduce” and then enter the matrix. The solution is x = 1 and y = -1. WolframAlpha understands several commands for putting an augmented matrix into reduced row echelon form. You can use the command rref { }or the command row reduce { }.

WebThe function Part can be useful, because it allows access to the rows and columns of a matrix. For example, mat [ [1]] returns the first row, and mat [ [All, 1]] is the first column. Assignments are also possible, e.g. mat [ [1]] = mat [ [1]] - 2 mat [ [2]] will modify the matrix in place by subtracting twice the second row from the first one.
