Once you have the idea of the structure, you should have little problem writing it. You can go for a non inductive presentation as well, but this I find easier to communicate.

| Aug 20, 2019 at 19:07 | comment | added | Durzot | Thank your for your answer. If I understand correctly you rewrite the matrix in a permutation of the canonical basis for $\mathbb{R}^{rd+r}$ so as to make $B$ appear in the upper left corner of size $r\times r$. If that is the case your idea is very similar to the idea in the post indicated by Robert Israel where no recurrence is needed. | |
