The process of row reduction makes use of elementary row operations, and can be divided into two parts. The first part (sometimes called forward elimination) reduces a given system to row echelon form, from which one can tell whether there are no solutions, a unique solution, or infinitely many solutions. The second part (sometimes called back substitution) continues to use row operations until the solution is found; in other words, it puts the matrix into reduced row ech… WebTo solve a system of linear equations using Gauss-Jordan elimination you need to do the following steps. Set an augmented matrix. In fact Gauss-Jordan elimination algorithm is divided into forward elimination and back substitution. Forward elimination of Gauss-Jordan calculator reduces matrix to row echelon form.
