Hello,
I'm developing a finite element code in fortran 90. I recently updated my PETSc
and am now getting the following error during compile/linking on an existing
application:
Undefined symbols for architecture x86_64:
"_petscfecreatedefault_", referenced from:
_MAIN__ in fe_test.o
When I want "full precision" for debugging purposes I use
PetscViewerPushFormat(viewer,PETSC_VIEWER_ASCII_MATLAB);

The implementation references the local matrix so you need to destroy
your copy. This pattern is always used when setting sub-objects like
this.
static PetscErrorCode MatISSetLocalMat_

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any res
Must I destroy the local matrix I have (created and) set with MatISSetLocalMat
?

Mainly for debugging purposes: controlling format/precision could be convenient
