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:
`http://www.mathworks.com/matlabcentral/newsreader/view_thread/134307

`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.
