Hello, I found a minor issue with the documentation for MatDenseSetLDA, which ended up causing my program to idle unexpectedly. In the documentation it is specified as "Not Collective". However, in the MPIDense implementation it is possible for PetscLayoutSetUp to be called, which is a collective. (Lines 201-202: https://petsc.org/main/src/mat/impls/dense/mpi/mpidense.c.html#MatDenseSetLDA_MPIDense)
Regards, Damian
