Hello,
I would like to know which inversion method is applied by Mathematica
when it computes the inverse of a symbolic matrix
Mat={{a,b,c},{d,e,f},{g,h,i}}; .
Taking a look at the result of Inverse[Mat]; may lead to the assumtion
that something like
adjugate[Mat]/Det[Mat]
is used ???
('adjugate' (adjoint) stands for a matrix whose elements are signed
cofactors or minor determinants)
Thanks in advance,
