I have the following segment:
M=matrix([[-3,1,1,1],[1,-3,1,1],[1,1,-3,1],[1,1,1,-3]])
b=var("b");
v = vector([1,b,b**2,b**3]);
AUG=M.augment(v,subdivide=true)
---------------------------------------------------------------------------
TypeError: unable to convert b to an integer
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)
