It was changed a while ago that MatSetBlockSize() couldn't be set after the matrix was full instantiated. I guess that example did not get fixed because it is not listed in the makefile to run in the makeall.

May I add it?

I have fixed the example to call MatSetBlockSize() at a safe point.

ex55.c in ksp is failing with:

[0]PETSC ERROR: --------------------- Error Message ------------------------------------ [0]PETSC ERROR: Arguments are incompatible! [0]PETSC ERROR: Cannot change block size 1 to 2! [0]PETSC ERROR: ------------------------------------------------------------------------

on this line 57 of ex55.c:

ierr = MatSetBlockSize(Amat,2); CHKERRQ(ierr);

Any idea what happened here?
