Gauss Jordan elimination (RREF) for Ax=0 which has *Infinitely many solutions*.
❖ Solve a linear system Ax=0 by using a Reduced Row Echelon Form (RREF).
(Sometimes, they called this method as Gauss Jordan elimination ( or Gauss-Jordan reduction) method). In this example, the answer to this system has infinitely many solutions.
❖ The method can process for Ax=b as the following
[A | b ] to [RREF | 0 ]
We have done RREF for the augmented matrix [A|0].
❖ Previously in this playlist, we have mentioned the steps to determine if a matrix is reduced row echelon form (RREF) or not.
Here, we have explained infinitely many solutions for the Homogeneous system Ax=0.
❖ The infinitely many solutions for Homogeneous system Ax=0 called nontrivial solutions.
