REDUCED ROW ECHELON FORM
REDUCED ROW ECHELON FORM We have seen that every linear system of equations can be written in matrix form. For example, the system x+ 2y + 3z = 4 ... Once the free variables are assigned values, we obtain a solution (x 1;x 2;x 3;x 4). The solution can also be written in vector form as 2 6 6 4 x 1 x 2 x 3 x 4 3 7 7 5 = 2 6 6 4 x 3 x 4 + 3 2x 4 ...

Lecture 8: Solving Ax = b: row reduced form R
ocw.mit.eduIf r = m, then the reduced matrix R = I F has no rows of zeros and so there are no requirements for the entries of b to satisfy. The equation Ax = b is solvable for every b. There are n − r = n − m free variables, so there are n − m special solutions to Ax = 0. Full row and column rank
