Hi,

I have a quick question, when should one use RREF in finding eigvenvectors? I've read through some books and sometimes they use them and sometimes they do not. I'm sorry for such a potentially stupid question.

Thanks,

It could be that having one in the pivot position position makes it easier to write system in parametric vector form. Otherwise row echelon form would suffice.

Where did you find that "they sometimes use them"? The row reduced form of a matrix does NOT in general have the same eigenvalues as the original matrix so I do see how row reducing could help.
