Not exactly. But you can make a Mat for each. Mark On Mon, Nov 14, 2022 at 8:59 AM Thomas Hisch <[email protected]> wrote:
Hi!
I would like to ask if it is possible to create a MatNest matrix that contains matrices, vectors and scalars.
My (jacobian) matrix looks like the following
[[A, B, a, b], [C, D, c, d], [e, f, g, h]]
where A-D are sparse square matrices, a-d are dense column vectors, e, f are sparse row vectors and g,h are just scalars.
Is there also a petsc4py example that shows how nest objects should be created and how they should be used?
Best regards Thomas
