Hi, I have a block matrix with type of MATNEST, but can I call -pc_fieldsplit_detect_saddle_point to change its IS? I assume it is not possible.
Also, I notice there is a small but important typo in the new fieldsplit doc: https://petsc.org/release/manualpages/PC/PCFIELDSPLIT/ The first matrix of the full factorization misses A10. I believe it should be [I -ksp(A00) A01] [ I ] Best, Qi
