Section 8.4 Alternative Minors/Cofactors Computation

Although there are no built-in methods in Sage to directly compute minors and cofactors are currently, we can leverage the command adjugate to compute them like shown below.
From the cofactors matrix, we then have access to cofactors \(c_{ij}\text{,}\) and from there to the minors \(m_{ij}\) like in the following example.
