If you want to augment M with symbolic elements it need 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]])
or alternatively you can keep the definition of M intact but change its ring just before the augmenation:
AUG=M.change_ring(SR).augment(v,subdivide=true)
