[petsc-users] matrix visualization problem

[Satish Balay]

well if you need -mat_view_draw - then suggest editing
src/mat/impls/aij/mpi/mpiaij.c and increate this cut-off size.

[there is now a command-line option to over-ride this limit in petsc-dev]

For binary viewer - check mat/examples/tests/ex31.c
