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… WebMar 31, 2011 · I mean, I solved with forward Gaussian elimination half of a matrix (under matrix there are zeros under diagonal) and then I have made backward substitution.
