RREF with unknown variables

Hi

Suppose I have an augmented matrix with unknown variables and I want to reduce it to its reduced row echelon form. How to do this in Matlab ?

Example matrix:

[1, 2, 3, a;

4, 5, 6, b;

7, 8, 9, c;]

Thanks for advance!

Hey

Thanks for the answer. I was not specific enough. So the issue was I couldnt assign variables (assigned by 'syms') to the "excel sheet" where I was assigning elements to it.

syms a b c
rref([1, 2, 3, a;
    4, 5, 6, b;
    7, 8, 9, c])

ans =
