Hi,
I would like to create a matrix aij with the same OwnershipRanges as an other
existing matrix with petsc4py. The two matrices have not the same non zeros
patern.
Any ideas ?

Dear petsc users,
I have parallel matrix A (mpiaij) and I would like to create a matrix B like
B = [A v
wT 0 ]
where wT and v are vectors.
A is involved in eigenvalue computation (slepc4py) and B will be used by a
direct solver.
Currently, the matrix A is built from a sparse scipy matrix th
Dear petsc-users,
I am a beginner in petsc and I have some question with the python interface. I
am trying to solve problem with mumps (or other direct sparse solver)
I have written the following piece of code
ksp = PETSc.KSP()
ksp.create(PETSc.COMM_WORLD)
ksp.setOperators(A)
