Can the object name be also displayed when the option -<object>_view is provided or <object>View() is called? Maybe only for matrices,vectors and DAs??
Instead of row 0: (0, 4) row 1: (1, 4) row 2: (2, 4) row 3: (3, 4) row 4: (4, 4) It should display Matrix Object : <matrix_name> row 0: (0, 4) row 1: (1, 4) row 2: (2, 4) row 3: (3, 4) row 4: (4, 4) Shri ----- Barry Smith <bsmith at mcs.anl.gov> wrote: > > I have added PetscObjectPrintClassNamePrefixType() which is now (in theory) > used uniformly in all the XXXView ASCII info formats to display this > information appropriately.
