Thanks for your answers! So my concern would be now to compute the
adjugate of a matrix. Can Eigen do better than computing all the minors
of the given matrix?

I guess there are not many practical uses for the adjugate matrix. From what I have learned it's more a concept to introduce the inverse of a matrix in linear algebra.

Here is a thread on how to (half-manually) compute the adjugate with Matlab, which should be portable to Eigen somehow:

Eventually, you should check whether you really need the adjugate. If you only need it for educational purposes, there would be nothing wrong with computing all minors separately.
