Reduced Row Echelon

Hi, did I quick search, didn't find anything like this, so there you go.

Simple enough question really, I need to put this matrix into reduced row echelon form:

0 0 0 4 | 0
0 0 3 3 | 0
0 2 2 2 | 0
1 1 1 1 | 0

I'm not sure why, but I really have a hard time wrapping my head around reduced row echelon, or even just row echelon. It's pretty basic, I just need to put it into reduced row echelon form so that I can find whether or not it's linearly dependent. Thanks, sorry for the dumb question

Re: Reduced Row Echelon

Hey, so basically reduced row echelon form is getting the whole matrix down to 1's and 0's (for the MOST part).

here are some examples:
1 0 *
0 1 *

1 * 0 0 * 0
0 0 1 0 * 0
0 0 0 1 * 0
0 0 0 0 0 1

where the *'s can be anything

you just use elementary row operations to it to look that way

hope that helped
