Get information on matrix

Question

Hello,

I am interested into getting some information on a PETSc matrix resulting from assembly process :

A = PETScMatrix()
assemble_system(a, L, bcs, A_tensor=A, b_tensor=b)

Is it possible to use PETSc's MatGetInfo function within petsc4py syntax ? Do someone have some experience with this ?

Thank you in advance,

Claire

Hi, MatGetInfo is not exposed in petsc4py. If you have cloned your own version of petsc4py, it is very easy to add this functionality, see here. Anyway, block_size field of the MatInfo is available as a property.
