Fantastic, it definitely solved my problem! Thank you!
Should I always create the vectors with MatCreateVecs when I use them for
matrix-vector multiplications? I used to create vectors with VecCreate, and
it has always worked fine with "standard" matrices (matrices not created
with MATNEST str

Thanks Dave, that's exactly what I was looking for, and it (partially)
solved my problem.
The MatMult operation now works fine, unfortunately not for every number of
MPI processes (while the MatMult involving each submatrix works fine for any
number of processes):
matArray(1) = L_discre

Hi,
I'm trying to set a linear problem with a 2x2 block matrix (say A=[A11 A12;
A21 A22] in matlab notation). Obviously I could generate a single matrix,
but I would like to keep it as a 2x2 block matrix with the 4 blocks
generated and used independently (e.g., because at some point I need to
