If you want to augment M with symbolic elements it needs to be defined over the symbolic ring SR. You can do so upfront via

M = matrix(SR, [[-3,1,1,1],[1,-3,1,1],[1,1,-3,1],[1,1,1,-3]])

Alternatively, you can keep the original definition of M intact, but change its ring just before the augmenation:

AUG = M.change_ring(SR).augment(v,subdivide=true)

That works..Thank you for the solution!
