Say I am given a matrix and am supposed to put the matrix in row echelon form, does swapping two rows change the final matrix? Say I have:

3 1 4
1 1 1
0 1 3

It would save time to swap the first two rows, however when I do that on my problems the first row is wrong.

I've found my answer.

Seems that REFs aren't unique and depend on the order and number of EROs.

Reduced row echelon forms should be unique, though.
