Lec 9 - Echelon Reduce Operations
Monday, January 23, 2012
A matrix is in reduced row echelon form (RREF) if:
(Note: Every Matrix has a UNIQUE RREF)
Since there is no choice of variables, this system is inconsistent.
The solution set of the system is
The solution set is
We must solve the system
A system of linear equations is homogeneous if the RHS contains only zeros.
Note: Performing ERPs on a homogeneous system will not change the RHS. We just perform EROs on the coefficient matrix.
