[petsc-users] Store only Matrix Structure (Binary)

[Thomas Hisch]

Hello list,

is it possible to store just the nonzero pattern of a large (sparse)
matrix in a file? If I write the whole matrix to disk
(PetscViewerBinaryOpen/MatView) its size is about 30MB. As I only need
its structure it would be a good idea to load and store just the
non-zero pattern of the matrix.

Has anyone tried to do that and are there corresponding functions in petsc-dev?

Regards
Thomas
