Re: [petsc-dev] change to MatIsTranspose() and failing test

28 Apr 2011


      Lisandro :
...
BTW, do you fully agree with my previous fix? Should MatIsTranspose()
generate an error if the test is not implemented? Or should it just
return PETSC_FALSE?
I agree with you: generate an error if the test is not implemented -
consistent with entire petsc style
'PETSC_FALSE' is simply one of output of this routine.

After wasting as considerable amount of time debugging issues related
to uninitialized variables passed to MatIsTranspose, I've pushed this:

summary:     MatIsTranspose(): error if any matrix does not support the test
And now, the best below fails, becase SeqBAIJ does not support transpose test.
[dalcinl@trantor tests]$ cd $PETSC_DIR/src/ksp/ksp/examples/tests
[dalcinl@trantor tests]$ make runex32_aij_sbaij_icc
