I've taken two upper division courses in linear algebra, and yet a trivial problem has arisen that I am having trouble answering! haha
Let A be the matrix:
[1 2 0 3]
[0 0 0 0]
[0 0 1 2]
Is A in RREF? I say yes, however, the majority of students whose papers I am grading say no. If they are correct, what is the reason?
TIA,
Ryan
